Call (301) 395-3831

Exterior window sealing fails in Potomac homes as temperature cycling expands and contracts the frame and siding over years. When the sealant cracks or separates, water gets into the joint, behind the siding, and into the rough opening. Our team removes old failed sealant completely, prepares the joint, and applies the correct exterior-grade silicone or siliconized latex in a clean consistent bead that bonds to both surfaces.

Potomac properties are often larger with more complex systems. Our team gives every job a proper diagnostic before quoting.

Frequently Asked Questions

Paintable siliconized latex for wood and fiber cement frame-to-siding joints. Pure silicone for glass-to-frame joints and aluminum frame transitions. Our team selects the correct product for the specific substrate in your Potomac home.

It must be removed. Applying new sealant over failed old sealant doesn't bond properly to the substrate. The new material fails quickly because it's adhered to loose old caulk instead of the window frame material itself.

It addresses one common entry point. If water is entering through a failed seal around the window frame, resealing stops that entry. If there are other sources such as flashing failure above the window or a failed IGU, those are separate issues. Our team notes any other visible causes during the visit.

A properly prepared and applied exterior sealant lasts five to seven years in Maryland's climate. Product quality and surface prep are the two biggest factors. Thin consumer caulk on an unprepared joint lasts one to two seasons.

What We See in Potomac Homes

Potomac is mostly large detached homes on large lots, built over the last forty to sixty years, with a smaller newer condo and townhome segment around Park Potomac. Most classic Potomac streets carry no mandatory HOA, and many pre-2000 houses still have their original kitchens and baths.

Exterior work therefore means longer runs and more surface to cover, so we scope the whole elevation rather than one spot.
