FAQ

Additions, answered.

If you're weighing addition vs. move, these are the questions to ask any contractor.

How long does an addition really take, start to finish?

Design + permits typically run 3–6 months. Construction runs another 4–8 months depending on scope. Plan on 7–14 months from first call to move-in for most projects.

Can we live in the house during construction?

For most additions, yes, we seal off the existing house with dust barriers and stage work to keep utilities running. Whole-home renovations or major MEP upgrades sometimes require temporary relocation; we'll tell you up front.

Will you handle all the permits, or do I?

We do. Architectural drawings, structural engineering, permit submittal, comment responses, inspections, all included in the fixed price.

What if the inspector finds something unexpected during construction?

Inspector findings are our responsibility, not yours. If we missed a code issue in design, we eat it. If the inspector requires something new, that's a documented change order and you sign for it.

How do you tie the addition into the existing roofline and siding?

We match shingle profile, color, and weather exposure on the roof. Siding gets matched at the supply level (we order from the same manufacturer when possible) and feathered with trim transitions where necessary.

Financing options for an addition?

Yes, through our third-party partner. Apply through our partner ↗, often used for primary-suite additions and in-law suites.

What types of home additions does Quick Remodels build?

We design, engineer, permit, and build second-story additions, in-law suites, kitchen and room extensions, and sunrooms, handling architectural design, structural engineering, permitting, foundation and framing, roofing and siding tie-ins, and full interior finishing on one fixed-price contract.

What areas does Quick Remodels build home additions in?

We're based at 7801 Old Georgetown Rd in Bethesda, MD and build additions throughout Montgomery County and the DC metro, including Chevy Chase, Potomac, Rockville, Silver Spring, Kensington, Gaithersburg, and Washington, DC.

How much does a home addition cost in the Bethesda area?

Most Bethesda-area home additions run from about $75,000 to $500,000+, depending on size, complexity, and whether it's a single-room extension or a full second-story build. Structural engineering and permits are included, and every project is quoted as one fixed price.

Is Quick Remodels licensed and insured?

Yes. Quick Remodels is a family-owned company founded in 2011, MHIC-licensed in Maryland (#133088) and licensed in Washington, DC (#410518000673), fully insured, with all trade work performed by licensed professionals and inspected.
