1989median year homes were built

What's on the ground in Gaithersburg

1989 is roughly the midpoint for when a Gaithersburg house went up, so plenty of the siding on these walls isn't original.

32% of the local housing stock is old enough to predate 1980, and houses that age rarely still wear their first exterior.

Median home value here sits at $496,500, the backdrop the 10 siding contractors below are pricing jobs against.

Siding contractors near Gaithersburg, ranked by Google rating

Each business's Google star rating gets discounted or boosted here by its own review count, so five stars from a couple of reviewers loses out to a 4.8 built on hundreds. That math tells you nothing about a license, so ask to see a contractor's license or registration yourself before you sign.

What exactly does the written estimate include: house wrap, flashing, trim, and site cleanup?
What does the manufacturer's material warranty cover, separate from your warranty on the installation itself?
How much is the deposit, and what triggers each remaining payment?
