Our team brings more than 25 years of combined industry experience, and we treat every project with the care we would give our own home. We serve Alexandria and homeowners across Northern Virginia.
From GAF-certified roofing to energy-efficient windows and doors, we install materials built to hold up through Virginia's hot summers, cold winters and everything between.
Our technicians are trained and certified, and they take care to do clean, precise work that is done right the first time, whether your home is a historic brick rowhouse or a newer build.
Every project — whether it's a single window or a full exterior renovation — is backed by Landmark's lifetime guarantee, so Alexandria homeowners can move forward with total confidence.

Will new windows and doors suit an older Alexandria home?
Alexandria has many older brick rowhouses, colonials and townhomes, from Old Town to Del Ray. We offer trim, grille and finish options chosen to match the look of the home.
How does Landmark handle installation on a tight street or limited parking?
We plan equipment staging and access when we schedule the job, so street width, parking and any HOA or condo loading rules are sorted out before install day.
Do I need approval to replace windows or doors on a historic home in Alexandria?
Possibly. Homes in Old and Historic Alexandria and the Parker-Gray historic district are reviewed by the City’s Board of Architectural Review, so exterior window and door changes can need approval before work starts. We explain what applies to your address and help you prepare, so you know before you order.
