Vinyl Siding, From the ProVia Certified Installer
JDH installs ProVia vinyl siding across Maryland and Virginia as a ProVia Certified Installer and VSI Certified Installer (Vinyl Siding Institute). ProVia is one of two siding brands JDH installs (the other is James Hardie for fiber cement). JDH installs five ProVia vinyl lines: CedarMax (insulated, our default workhorse with R-2.2 to R-2.8, 5 times the impact resistance of standard vinyl, and up to 39 percent sound reduction), Cedar Peaks (the same .046 to .050 inch vinyl as CedarMax, non-insulated, for homeowners who want the look and durability without the foam upgrade), Willowbrook (.042 inch with six profile widths, the most design variety), Ultra (.040 inch entry-tier with the cleanest budget value), and Traditional (.046 to .048 inch beaded or 8 inch clapboard for historic and minimalist American architecture). Every line carries ProVia’s Lifetime Limited Warranty plus the JDH 5-year transferable workmanship warranty. JDH refuses to install Allura, Mastic, Alside, CertainTeed Vinyl, Royal, and other lower-tier brands. The forensic PCC inspection is free. See the vinyl siding cost spoke for installed pricing.
Pricing at a glance
ProVia vinyl siding installed by JDH runs $725 to $1,250 per square with a $2,500 minimum job. The lead-tier insulated CedarMax sits at the upper end; non-insulated Cedar Peaks, Willowbrook, and Ultra sit lower. Prep complexity (existing siding tear-off, sheathing repair, weather barrier upgrade) and elevation count also move the per-square cost. For the full breakdown by ProVia line, the line-by-line price comparison, monthly financing math, and the cost of bundling vinyl into a roof replacement, see the vinyl siding cost spoke. The forensic PCC inspection is free for homeowners.

Five ProVia vinyl siding lines. Which one is right for your home.
JDH installs five ProVia vinyl lines, sequenced from the lead-tier insulated workhorse to the entry-tier value play. The right one depends on three things: how much you want to invest in insulation and impact resistance up front, how much profile and color variety matters for your architectural style, and where you want the per-square cost to land. Here is when to pick each.
CedarMax (insulated)
JDH’s default ProVia vinyl install. .046 to .050 inch panel with rigid EPS foam backing for R-2.2 to R-2.8 of continuous insulation. Five times the impact resistance of standard vinyl, up to 39 percent sound reduction. 28+ colors across the Lifestyle and Signature collections. Four profiles including Single 7 inch, Double 6 inch, Triple 4 inch Dutch Lap, and Board and Batten. Pick CedarMax when you want premium energy performance, the thickest panel projection, and the longest install life out of vinyl.
Verify product specs
Cedar Peaks (non-insulated)
The same .046 to .050 inch vinyl quality as CedarMax, just without the foam backing. 27+ colors, four profiles, same patented Twister Lock and Cyclonic Locking System, same Lifetime Limited Warranty. Pick Cedar Peaks when you want the CedarMax durability and aesthetic without the insulation premium, typically because the home already has wall-cavity insulation or the budget needs the vinyl to step down without giving up panel thickness.
Verify product specs
Willowbrook
.042 inch panel with brushed cedar woodgrain finish. Six profile widths available, the most variety in the ProVia vinyl lineup: Double 5 inch Lap, Double 4.5 inch Lap, Double 5 inch Dutch Lap, Double 4 inch Lap, Double 4.5 inch Dutch Lap, and Double 4 inch Dutch Lap. 20+ colors. Pick Willowbrook when profile and design variety matter more than maximum panel thickness, often on custom-built or architecturally distinctive homes where matching the right lap width to the elevation matters.
Verify product specs
Ultra
.040 inch panel, the thinnest in the lineup. Soft woodgrain finish, 10+ Lifestyle Collection colors, three profiles (Double 5 inch Dutch Lap, Double 4 inch Dutch Lap, Double 4 inch Lap). Lifetime Limited Warranty stays. Pick Ultra when budget is the controlling factor and the home doesn’t need premium panel thickness or insulation, typically on smaller homes, single-elevation matches, or rental property installs where the cost-per-square has to land at the floor of the range.
Verify product specsTraditional
For minimalist or historic American architectural styles. Two profiles: 6.5 inch beaded (.048 inch with cedar woodgrain texture) or 8 inch single clapboard (.046 inch with matte finish, white only). 19 colors on the beaded; clapboard is white only. Pick Traditional when you want the simpler, less ornate elevations that 1700s and 1800s American colonial and farmhouse styles call for, where six-inch lap looks busy and the wider clapboard reads correctly.

JDH-employed inspector + 5-year workmanship
Whichever ProVia line you choose, the install is the same: JDH-employed forensic inspector walks every elevation, tear-off down to the sheathing, synthetic housewrap weather barrier, ProVia installed to ProVia spec with the post-formed lock engaged, color-matched trim, the ProVia Lifetime Limited Warranty registered on your behalf within two business days, and the JDH 5-year transferable workmanship warranty on top.
JDH siding warrantyIf your existing siding repair would cost more than 35 percent of new ProVia vinyl, replace.
JDH applies the same 35% Rule to siding that we apply to roofing. If a fair repair quote on your existing vinyl (or T1-11, or aluminum, or whatever is there now) lands at 35 percent or more of full ProVia replacement, replacement is the responsible call. The most common scenario: cracked and warping vinyl across multiple elevations, rotted T1-11 plywood siding, or hail damage spread across three sides. Patching multiple elevations with mismatched material is rarely the value the homeowner thinks it is.
What it looks like in practice: a 10-year-old roof comes in with one bad valley and a flashing rebuild at $7,200. Full replacement on that roof is around $22,000. The repair lands at 33% · under the threshold, repair makes sense and carries our 5-year workmanship warranty.
Same roof a year later, after another storm, comes back with the original scope plus a chimney rebuild and 60 square feet of decking. Repair quote is $9,200. Replacement still around $22,000. That’s 42% · over the threshold. We tell the homeowner replacement is the responsible call, walk through the system shown on this page, and apply the diagnostic fee as deposit if they move forward. See replacement cost for the deeper price breakdown.
Where the “25% Rule” you’ve heard of actually comes from.
Most cost-guide content on “when to replace a roof” quotes the 25% Rule. Worth knowing where 25 comes from: the Florida Building Code. After Hurricane Andrew, Florida code officials wrote a re-roofing rule (in the Florida Building Code Existing Building chapter, often called the “25% Rule” on contractor forums) that says if more than 25 percent of a roof is repaired or replaced inside any 12-month period, the entire roof has to be brought up to current Florida wind-uplift code.
It’s a hurricane-country regulatory trigger, not a homeowner replacement-decision framework. Maryland and Virginia building codes don’t carry that provision. Contractors elsewhere have repurposed the 25 percent number nationally as a loose heuristic, but the Florida rule and a roofer’s replacement recommendation aren’t measuring the same thing:
- 25% (Florida code): Are you legally required to re-roof? “Yes” once you’ve touched a quarter of the area inside 12 months.
- 35% (JDH ethics): Is replacement the responsible call on this specific roof? “Yes” once a fair repair quote crosses a third of what a full replacement costs.
Two different questions, two different thresholds, neither one substitutable for the other. The 35 percent number is where JDH inspectors kept landing after looking at thousands of MD and VA roofs. It’s the point where the homeowner stops getting their money’s worth from a repair, regardless of what any building code requires.
Why our floor is $725 per square. And what a $4 per square foot vinyl install actually buys.
If you have seen $4 to $5 per square foot vinyl siding quotes (roughly $400 to $500 per square installed), you have probably wondered how a real JDH ProVia install could be twice that or more. Here is what gets skipped to hit that price.
- No PCC forensic inspection. The budget install measures from the curb and quotes the visible elevations. JDH walks every elevation, opens suspect penetration points, and identifies the sheathing repair you actually need before the existing siding comes off.
- Over-siding instead of tear-off. The budget install lays new vinyl over the existing siding to save labor. Trapped moisture rots the sheathing in 18 months, and any manufacturer warranty is voided from day one.
- No housewrap upgrade. The budget install reuses the existing weather barrier (often degraded asphalt felt). JDH installs a code-approved synthetic housewrap on every install. The housewrap is what makes the system watertight, not the vinyl.
- Generic .032 inch vinyl, not ProVia. The budget install uses Allura, Mastic, Royal, or unbranded vinyl, typically .032 to .038 inch thick (vs ProVia’s .040 to .050 inch). None of those carry ProVia’s Lifetime Limited Warranty. JDH refuses to install them because we have no faith they will last.
- No trim or corner-post detail work. The budget install caulks over the gaps at corners, around windows, and at roofline transitions. JDH installs color-matched J-channel, corner posts, and head flashing at every transition. This is what turns a basic vinyl install into a finished home.
- Workmanship warranty measured in days. JDH’s 5-year transferable workmanship warranty is non-negotiable on every install. A 30-day or 1-year workmanship warranty is industry-standard at the budget tier.
None of this is a knock on the homeowner who picks the budget install. The price is real, somebody shows up, vinyl gets nailed on. But ProVia vinyl installed to spec lasts 30 to 40 years. Budget vinyl installed badly lasts 8 to 12. JDH’s $725 per square floor is what an honest install costs when the elevation gets inspected, the existing siding gets torn off, the sheathing gets repaired, the housewrap goes on, the ProVia gets installed to spec, and the manufacturer warranty actually registers. See financing if budget is the actual concern.

Five steps, same process every time, whether the install is a single dormer elevation in Cedar Peaks or a full-wrap two-story colonial in CedarMax insulated.
1 You call · we answer live +
A real JDH team member takes the call, not an answering service. We confirm your address is inside our 90-mile service radius, ask about the roof’s age and what prompted the call, and schedule the free inspection. If you’re not sure replacement is even necessary yet, that’s exactly what the inspection settles.
2 HAAG-certified inspection · PCC Method +
A Design Specialist (the JDH name for our field inspectors: Joey Walzel, Tom Raley, Sam Carts, or Matt Brown, with Inspector Manager Brian McClees leading the team) walks the roof with FLIR thermal, drone, GoPro, snake camera, moisture meter, and HAAG shingle gauges. Decking condition, ventilation balance, and flashing age all get measured, not eyeballed. Every finding is documented as Problem, Cause, Consequence: the PCC Method.
3 35% Rule applied · the honest recommendation +
The inspection data runs through the 35% Rule. If a fair repair would cost less than 35 percent of replacement and the roof has serviceable life left, we tell you to repair it, not replace it. If repair crosses the threshold, or the roof is simply past its serviceable life, replacement is the recommendation and you get the written reasoning, not a sales pitch.
4 Digital Analysis video · written quote +
You receive a written photo and video report with PCC commentary on every finding, plus an itemized replacement quote: shingle line and color, underlayment, ice-and-water coverage, ventilation corrections, and deck repair allowance all named on the contract. If storm damage is involved, the documentation is structured the way insurance carriers expect, though JDH does not act as a public adjuster. See the claims walkthrough.
5 Replacement installed · 50-year + 5-year warranty +
Most full-wrap ProVia vinyl installs in Maryland and Virginia run 4 to 7 working days depending on home size, weather, and the number of elevations: existing siding tear-off, sheathing inspection and repair, synthetic housewrap, ProVia installed to spec with the post-formed lock engaged at every panel join, color-matched corner posts and J-channel at every transition, magnet sweep. The ProVia Lifetime Limited Warranty is registered on your behalf within two business days. JDH 5-year transferable workmanship warranty on top. Dump trailer stays on the street, not the lawn.
Two siding brands. ProVia and James Hardie. That is it.
JDH installs ProVia for vinyl-style and composite profiles and James Hardie for fiber cement. We have refused brands we do not install for a reason: we like to keep things simple, and when we shake your hand and say it will last we need to have faith in two things, the install crew and the products. ProVia and Hardie we know. The rest we leave to other contractors.
JDH is a ProVia Certified Installer and VSI Certified Installer (Vinyl Siding Institute). Five ProVia vinyl lines JDH installs: CedarMax (insulated default), Cedar Peaks (non-insulated equivalent), Willowbrook (six profile variety), Ultra (entry tier), and Traditional (beaded and clapboard for historic homes).

ProVia Vinyl Siding FAQ
Which ProVia vinyl siding line should I install on my Maryland home? +
JDH installs five ProVia vinyl lines. The decision usually comes down to insulation, profile variety, and budget. CedarMax (insulated, R-2.2 to R-2.8) is the JDH default when you want premium energy performance and the thickest panel. Cedar Peaks is the same vinyl quality without the foam backing, for homeowners who already have wall-cavity insulation or want the CedarMax durability without the insulation premium. Willowbrook offers the most profile variety (six widths) at a .042 inch panel. Ultra is the entry tier at .040 inch. Traditional is for historic and minimalist American architectural styles (6.5 inch beaded or 8 inch single clapboard). The free PCC inspection identifies the right line for your specific elevation and architectural style.
Is insulated vinyl siding worth the extra cost in Maryland? +
For most Maryland and Virginia homes built before the early 1990s, yes. Older wall framing has uninsulated studs that conduct heat directly through the wall, and the studs themselves often account for 15 to 25 percent of the wall surface. CedarMax adds R-2.2 to R-2.8 of continuous insulation over the entire wall, including the studs that were never insulated. The energy savings typically pay back the upgrade premium over 8 to 12 years. Beyond energy, CedarMax adds five times the impact resistance of standard vinyl and up to 39 percent sound reduction, which matters on busy roads, near Naval Air Patuxent River, or wherever neighborhood noise is a daily reality.
How long does ProVia vinyl siding last? +
ProVia vinyl installed to spec lasts 30 to 40 years in Maryland and Virginia conditions, with the ProVia Lifetime Limited Warranty covering fading, chalking, cracking, peeling, and thermal expansion during that period. The shorter end of that range is typical for installs that take direct afternoon sun on the south and west elevations; the longer end is typical for shaded or wooded lots. By comparison, budget vinyl (.032 to .038 inch) installed badly lasts 8 to 12 years before the panels start cracking at the locks and the finish chalks visibly. The thickness difference is the single biggest predictor of vinyl lifespan.
Should I tear off old siding or install vinyl over it? +
Tear off, every time. Installing vinyl over existing siding traps moisture between the layers, accelerates sheathing rot, and creates an uneven nailing surface that defeats the ProVia post-formed lock system. Budget installers quote "over-siding" to save 10 to 15 percent of labor cost. The savings disappear within 18 months when the trapped moisture starts showing up at penetrations. JDH tears off existing siding on every install, inspects and repairs the sheathing, installs a synthetic housewrap, and installs ProVia to the manufacturer spec.
CedarMax vs HardiePlank: which is better for a Maryland home? +
Different materials, different homeowner priorities. CedarMax (insulated vinyl) wins on installed cost, low maintenance (no repainting, ever), and energy efficiency from the foam backing. HardiePlank (fiber cement) wins on fire resistance, the most premium curb appeal, and the longest warranty stack (30-year Hardie substrate + 15-year ColorPlus finish). CedarMax installs faster (4 to 7 working days on a full wrap vs 5 to 8 for Hardie) and costs roughly 20 to 30 percent less per square installed. Homeowners pick CedarMax for energy and long-term low-maintenance; Hardie for curb appeal, fire performance, and resale strength on premium homes. JDH walks the comparison during the inspection. See the vinyl vs fiber cement comparison for the full decision matrix.
Why does JDH refuse to install Allura, Mastic, Royal, and other vinyl brands? +
JDH installs two siding brands, period: ProVia for vinyl-style profiles and James Hardie for fiber cement. JDH refuses to install Allura, Nichiha, LP SmartSide, Mastic, Alside, CertainTeed Vinyl, Royal, Variform, Boral, and a dozen other brands. The reason is simple: JDH likes to keep things simple. When JDH shakes your hand and says the install will last, JDH needs to have faith in two things, the install crew and the products. ProVia and Hardie JDH knows. The rest JDH leaves to other contractors.
How long does a vinyl siding install take? +
Most full-wrap single-family ProVia vinyl installs in Maryland and Virginia run 4 to 7 working days depending on home size, weather, and elevation count. A single-elevation install (one side or a dormer wrap) is typically 2 to 3 days. Steps include existing siding tear-off, sheathing inspection and repair, synthetic housewrap, ProVia installed to spec with the post-formed lock engaged at every panel join, color-matched corner posts and J-channel at every transition, magnet sweep, and walkthrough. JDH schedules a specific calendar window, not an all-summer maybe.
Can vinyl siding be installed in winter in Maryland? +
Yes, with caveats. Vinyl panels become brittle below freezing and can crack during cutting and fastening, so JDH avoids installs in days that stay below 40F. Below 50F, panels need to warm in the truck before install and are cut with carbide blades instead of utility knives. Above 50F is the comfortable install window; 60 to 80F is the sweet spot. Winter installs in Maryland and Virginia are routine on milder days; the colder weeks shift to next-week scheduling. JDH does not push installs through weather that puts the warranty at risk.
Will homeowner insurance cover vinyl siding replacement? +
For damage from a covered peril (wind, hail, fallen tree, fire, lightning, vandalism) most Maryland and Virginia policies cover repair or replacement after your deductible. Age-related wear, finish chalking, and panel warping on uncovered siding are generally excluded. JDH documents siding claims with HAAG Master Level forensic findings, photo evidence, and Xactimate-formatted scopes of loss. JDH does not act as a public adjuster; the coverage decision belongs to the carrier.
Does JDH offer financing for a vinyl siding install? +
Yes, through Service Finance Company. Promotional 0% APR options are available for qualified Maryland and Virginia homeowners; most homeowners land around 6.99% APR over 10 years, subject to credit approval. Approved financed jobs require no deposit; non-financed jobs require a one-third deposit at contract signing, which is the legal maximum in Maryland and Virginia. See financing for current promotional windows.
