Fascia and soffit repair in Washington, DC

Most fascia rot we cut out starts with water getting behind the gutter. Missing drip edge, a gutter hung too low or overflow from clogged troughs keeps the top of the board wet for days after every storm. Painted pine and fir fascia on 1940s and 1950s colonials around Arlington and Silver Spring holds up for decades until the paint cracks, then it soaks up water like a sponge.

Soffits suffer differently. Plywood and beadboard soffits on older homes delaminate and sag once water reaches them from above, and the gaps that open at the joints are an open door for squirrels, starlings and bats. In wooded parts of upper Northwest and Montgomery County, we find chewed entry holes at the soffit corners more often than anywhere else on the house.

On rowhouses, the front cornice is usually a decorative wood or pressed metal piece, and the eave trim is limited to the porch roof and rear additions. Those porch fascias rot quickly where the gutter outlet sits, because one spot carries all the water from the porch roof.

The visible board is only part of the story. We probe the fascia with an awl every couple of feet, then pull a section of gutter if needed to look at the top edge and the rafter tails behind it. Rafter tails that crumble at the ends need to be sistered or capped before new fascia can be fastened.

From the attic, we check whether the roof deck along the eave is stained or soft and whether insulation is pushed tight into the soffit, blocking airflow. Blocked soffit vents trap warm, moist air in the attic, which feeds condensation and, in winter, ice at the eaves. If we see that, we'll talk about attic ventilation as part of the fix.

You'll get a quote that separates the board replacement from any rafter tail or decking repair, so you know what's routine and what came from water sitting there for years.

Cellular PVC trim boards don't rot, take paint well and hold screws firmly. They're our usual choice for fascia on suburban homes and rear additions, especially behind gutters. PVC moves more with heat than wood, so we leave small gaps at the joints and seal them with a flexible adhesive rather than butting boards tight.

Primed, back-sealed wood still makes sense on historic facades where the profile has to match, and in historic districts such as Mount Pleasant, Cleveland Park or Capitol Hill where visible trim changes may need sign-off from the Historic Preservation Office. We prime all six sides, including cut ends, before the board goes up.

Aluminum coil wrap over sound wood is a common low-maintenance finish. It works only if the wood underneath is dry and solid; wrapping rotted fascia hides the problem until the gutter falls off. We bend the wrap on a brake on site so it fits the board size exactly.

• Cellular PVC: no rot, ideal behind gutters
• Primed wood: historic profiles and painted trim
• Aluminum wrap: low upkeep over sound wood
• Vented vinyl or aluminum soffit: airflow plus animal stop

When we rebuild a soffit we install continuous vented panels or a strip vent wherever the attic needs intake air, and solid panels where it doesn't. Baffles go in at the rafter bays so insulation can't block the vent. That small detail helps the roof shed heat in summer and cuts condensation in winter.

If animals are already in the attic, they need to be out before we close the holes. We don't trap or remove animals ourselves; a wildlife control company handles that, and we come back to seal the entry points with metal flashing behind the trim. Closing a hole with a squirrel still inside just creates a new hole the next morning.

Old beadboard soffits on porches can often be saved. We replace only the rotted boards, match the bead profile and repaint, which keeps the look of a Takoma or Brookland porch intact.

New fascia behind a failing gutter will rot again. Every repair includes a look at the gutter pitch, the hangers and the drip edge. We add drip edge or a gutter apron under the first course of shingles where it's missing, so roof water lands in the gutter instead of running behind it. If the gutters themselves are worn out, it's cheaper to replace them while the fascia is open; see gutter installation for that work.

Roof edges where shingles hang too far past the board, or stop short of it, also feed rot. We trim or extend the edge detail as part of the repair. For an older roof with several problems at the eave, a full roof inspection helps decide whether to fix the edge or plan a replacement. Ring (202) 771-7443 and we'll come probe the trim with you.
