Vinyl siding services
- Full siding replacement: removal of old siding, wall sheathing repair, new housewrap and new siding

- Siding repair: panels cracked by impact, cold or storms, matched as closely as possible
- Trim, soffit and fascia: aluminum wrap and vented vinyl soffit
Siding and roofing work together
Where a roof meets a wall, at dormers, additions, porch roofs and chimneys, the step flashing must tuck behind the siding and weather barrier. When siding and roofing are installed by different crews without coordination, this detail is where leaks begin. Because we do both, we can sequence the work correctly, especially when siding replacement happens alongside a roof replacement. We also detail the fascia so new gutters mount securely.
- Housewrap (weather-resistive barrier) behind the siding. The flashing laps under it so water stays on the outside.
- Step flashing: one L-shaped piece per shingle course, each lapping over the piece below it. Continuous "L" flashing or caulk alone is a common leak source.
- Siding stops above the roof, leaving a clearance gap so it does not wick water or trap debris.
- Kick-out flashing at the bottom turns water away from the wall. Without it, water runs behind the siding and rots the wall.
- Gutter catches the diverted water.
What a quality vinyl siding install includes
- Weather-resistive barrier (housewrap) lapped shingle-style, with taped seams
- Flashed window and door openings
- Kick-out flashing where roof edges meet walls, to direct water into the gutter and away from the wall
- Panels nailed loosely enough to expand and contract with temperature, per manufacturer instructions
- Insulated siding options where added wall R-value makes sense
Permits and historic properties
Montgomery County's homeowner permit guide lists siding among work that most likely does not need a county permit. Exempt work must still meet the building code, and municipalities and HOAs may have their own rules. Exterior work on historic property is listed as requiring a permit. In historic districts such as the Chevy Chase Village Historic District, replacing original wood siding with vinyl is a significant material change that goes through Historic Preservation Commission review, so check before planning.
Managing water behind the siding, not just on it
In a mixed-humid climate, siding is only the first half of a wall's water management system; the half that actually keeps the house dry is what sits behind it. When we strip old siding off a Bethesda or North Bethesda house, the same findings come up again and again: housewrap missing entirely or lapped the wrong way so it funnels water inward, no flashing over window and door heads, and rot concentrated in one place, low on the wall where an upper roof dies into it, because there was never a kick-out flashing to throw water out into the gutter. Siding replacement is the one moment those things can be corrected at reasonable cost, so we photograph the sheathing before anything is covered and show you what we found. Where the roof edge or flashing is the source, it gets fixed as roof repair rather than wrapped over.
Local exposure then drives the material decisions. North and east-facing walls shaded by the tree canopy grow the same airborne algae that streaks north roof slopes, so very light colors on those elevations show it and need periodic washing. South and west walls take heavy UV, and darker vinyl in particular should be kept away from grills and reflective window glass, where concentrated heat can distort a panel. The most common cause of siding and trim damage we are called about, though, is not sun or color at all: it is a debris-choked gutter overflowing down the same section of wall storm after storm. Fixing that at the source through gutter repair or properly sized gutter installation protects the new siding far more than any product upgrade.
Approvals vary sharply by address in our service area, so they are worth settling first. Across most Bethesda and North Bethesda subdivisions and townhouse communities, vinyl is widely accepted subject to HOA review of color and profile, which usually means submitting samples and allowing committee time. In the Chevy Chase Village Historic District the calculation is different: replacing original wood siding with vinyl on elevations visible from the public right-of-way draws scrutiny in historic review, and that application needs manufacturer data, photographs and specifications, which we prepare. On any house where the roof is also near the end of its life, doing both together while access and staging are already in place is both cheaper and better detailed, because the roof-to-wall flashings are installed in the correct sequence with the wall rather than cut in afterward, which is why we often quote it alongside a roof replacement. Our siding overview covers how the wall, the roof edge and the gutters work as one system.

Frequently asked questions
Can vinyl siding go over existing siding?
It sometimes can, but we generally recommend removal so we can inspect and repair the sheathing, install a proper weather barrier and flash openings correctly.
Can you repair a few damaged siding panels?
Yes. We replace individual panels. Older or faded siding may not match new panels exactly, and in that case we can sometimes swap in panels from a less visible wall.
