Siding Installation & Replacement in Washington, DC
Why DC Siding Projects Need Local Preservation Expertise
🏛️ The DC Historic Preservation & Rowhouse Case — Explained Honestly
- Most of DC's older rowhouse fabric sits inside a historic district: With 54 historic districts covering roughly 27,000 buildings, neighborhoods like Capitol Hill, Georgetown, Dupont Circle, Cleveland Park, Kingman Park, and large sections of Petworth are subject to preservation review for exterior work. More than 95 percent of cases are cleared through the HPO's Expedited Review, with same-day approval possible for in-kind repairs — but a full siding replacement using a different material is more likely to need full HPRB review, which meets only twice a month.
- Front-facade material rules are stricter than most homeowners expect: Documented HPO staff guidance has held that fiber-cement products like James Hardie are not approved for a historic rowhouse's front-facing elevation, even as they're routinely accepted on rear and side walls. Some districts carve out their own exceptions — Kingman Park's design guidelines specifically permit new cementitious siding on frame houses and don't require strict wood-for-wood replacement, reflecting that district's own preservation priorities. Getting the material recommendation wrong on a front elevation means a rejected application and a redesign.
- Georgetown runs on an entirely separate review process: Georgetown is the one DC historic district where the city's own HPRB is not the primary authority. The US Commission of Fine Arts, through its Old Georgetown Board, reviews exterior work visible from public space — a federal process layered on top of, not instead of, the standard DC Department of Buildings permit. A Georgetown siding project filed as a standard HPRB case is filed with the wrong body entirely.
- The stakes for skipping review are real: The 2024 Protecting Historic Homes Amendment Act allows the city to fine unpermitted historic-district work up to $25,000 per violation. This isn't a rule DC treats as symbolic — proper sequencing of HPO or HPRB review before a Department of Buildings permit application matters on every historic rowhouse project.
Siding Services We Offer in Washington, DC
Siding Types for DC's Historic Rowhouses
Wood & Wood-Look Historic Siding
Our recommended material for street-facing elevations of a rowhouse inside a DC historic district. Traditional wood clapboard or shingle, or a wood-look substitute where HPO precedent allows one, is the default expectation for front facades under most district guidelines, since fiber cement has generally not been approved for this elevation. Profile, reveal, and paint color matched to the district's design guidelines and any existing HPO precedent.
James Hardie Fiber Cement — HardiePlank
Our top recommendation for rear and side elevations not visible from the public right-of-way, and for any elevation on non-historic DC properties. HardiePlank's durability and 15–20 year factory finish make it the strongest long-term value where HPO restrictions on front-facing fiber cement don't apply. Kingman Park's own guidelines explicitly allow cementitious siding on frame houses, including street-facing walls in that district.
Insulated Vinyl Siding
A strong value option for DC rowhouses outside the 54 historic districts, particularly on frame-construction homes with minimal original wall insulation. Insulated vinyl adds R-2 to R-4 of continuous foam insulation during the same replacement project. Not typically permitted on historic-district front facades, but a straightforward option elsewhere in the city.
LP SmartSide Engineered Wood
A middle option for both rear/side elevations and, in some districts with flexible substitute-material guidelines, front facades — HPO staff evaluate engineered wood products case by case where true wood replication isn't feasible. LP SmartSide's grain texture suits DC's Victorian and Federal-style rowhouse stock. Paint intervals of 8–10 years.

Signs Your DC Home Needs New Siding
Delaminating Wood Shingles
Peeling, curling, or delaminating original wood shingle or clapboard siding on Capitol Hill and Cleveland Park's Victorian and early-20th-century rowhouses.
Deteriorated Non-Original Siding
Swelling, crumbling, or rot on non-original aluminum, masonite, or vinyl added during a prior renovation — common on DC frame houses.
Severe Color Fade
Washed-out, chalky color that cleaning or repainting cannot restore — the siding surface has degraded beyond cosmetic remedy.
Interior Water Stains
Water marks on interior walls near exterior surfaces — active infiltration at failed siding seams, often worse on party-wall rowhouses.
Rot at Cornices & Trim
Soft or crumbling wood at cornices, window casings, and door surrounds — a frequent early sign of moisture behind aging DC rowhouse siding.
Cold Exterior Walls in Winter
Interior wall surfaces cold to the touch on frame-construction DC rowhouses with minimal original wall insulation.
Navigating DC's Historic Preservation Review Process
🏛️ The DC preservation reality: Before recommending a material, we confirm whether a DC property sits within one of the city's 54 historic districts, and if so, which review path applies. For straightforward in-kind repairs, the HPO's Expedited Review can clear a Department of Buildings permit application same-day. For a fuller siding replacement changing material or profile, the case may need full Historic Preservation Review Board review, which meets twice monthly — so we build that timeline into the project schedule from the start. In Georgetown, we prepare a submission for the US Commission of Fine Arts' Old Georgetown Board instead of a standard HPRB case, since that district's review authority is federal rather than local. Once preservation approval is secured, we file the DC Department of Buildings permit with the approved plans attached.
Our Siding Installation Process in Washington, DC
Free In-Home Estimate — Historic Status & Elevation Review Included
We visit your DC rowhouse and assess the full exterior — siding condition and material on each elevation, age and failure mode, sheathing condition, and insulation opportunity. We confirm whether the property sits within a historic district, which review body applies, and which elevations face front-facade material restrictions. Material samples and district-specific precedent presented at this appointment. No charge, no obligation.
Material Selection — Matched by Elevation and District
We recommend wood or wood-look material for street-facing elevations on historic-district properties, and James Hardie, LP SmartSide, or insulated vinyl for rear and side elevations or non-historic homes. Options presented with an honest comparison of cost, durability, and the realistic preservation-review path for each.
HPO, HPRB, or Old Georgetown Board Submission
Where required, we file through the HPO's Expedited Review for in-kind or precedented work, or prepare a full HPRB submission with elevation drawings and material specifications for larger changes. For Georgetown properties, we prepare the corresponding Old Georgetown Board submission instead. Once preservation approval is secured, we file the separate DC Department of Buildings building permit.
Old Siding Removal & Sheathing Inspection
Existing wood, aluminum, masonite, or vinyl siding removed carefully, with attention to shared party walls common on DC rowhouses. Sheathing condition assessed after removal, with damaged sections replaced before house wrap is installed. Lead-safe disposal practices used on DC's older pre-1978 homes.
House Wrap, Siding & Trim Installation
Continuous weather-resistant barrier installed across all elevations, individually flashed at every window, door, and penetration. New siding installed to the reveal and profile specified in the approved preservation plans where applicable, with cornices, window casings, and trim restored or matched to the home's architectural period.
Final Inspection, Caulking & Exterior Walkthrough
Every seam, transition, and penetration inspected. All exterior joints caulked with flexible, paintable exterior-grade sealant. Full debris removal, coordinated with DC's rowhouse alley access where applicable. Exterior walkthrough with you before project close. Written warranty. Preservation conditions of approval and permit sign-off closed out where applicable.

What Washington, DC Homeowners Say About DMV General Contracting Group
"Our Capitol Hill rowhouse's front facade had deteriorated original wood siding. DMV General Contracting Group was upfront that James Hardie wasn't going to get approved on the street-facing wall, and steered us to a wood-look material with real precedent in our district instead. HPO cleared it through Expedited Review — no full board hearing needed."
"We're in Georgetown and had no idea the review process was totally different from the rest of the city until DMV General Contracting Group explained the Old Georgetown Board and the Commission of Fine Arts process. They prepared that submission specifically instead of treating it like a standard HPRB case, which saved us from a filing that would have gone to the wrong body."
"Our Kingman Park frame house needed full siding replacement, and DMV General Contracting Group knew our district's guidelines specifically allow cementitious siding on frame houses — no wood-for-wood requirement. We got James Hardie on the front facade, which I understand isn't typical in most DC historic districts."
"Our Petworth rowhouse isn't in a historic district, so DMV General Contracting Group confirmed that upfront and we moved straight to James Hardie across every elevation without any preservation review at all. Simple, fast permit, ten days start to finish."
