"I spoke with Keith on the phone and he told me he could probably come the next day for an estimate but would have to call me back to let me know. I waited all evening, really excited that he could come by so quickly but I never received a call back.***Update: I received a call 2 days later and an apology for the call being late. he was able to come by that same day for an estimate! Very professional in that sense. Waiting for my estimate now. Will update after work is complete if I go with this company.***Update: The price I was quoted is completely fair and THOUSANDS under big name companies. Excited to have my pool deck built by this company!"

Our thanks to Keith Nevins of Nevins Construction for the outstanding job on our deck project. He and his crew did a fantastic job replacing our rotting deck. The craftsmanship is outstanding, the deck pleasing to the eye as well as sturdy and functional. And the crew did an awesome job cleaning up everything afterwards which was very important to us.

Nothing slows down a deck project like permit delays or HOA pushback. Here’s what you should know:
Most substantial deck or outdoor living additions in Gaithersburg require Montgomery County permits. We handle all paperwork, drawing, submittal, and inspection.
HOA approvals: If your neighborhood (e.g., Kentlands, Lakelands) is in a homeowners association, expect design review. We help assemble what you need.
Approximate costs: Wood decks often start lower but need maintenance; composite/PVC will cost more up front (~$20–40/sq ft depending on style/features) but offer long-term savings.
We serve all over Gaithersburg and surrounding areas, including:
Kentlands
Lakelands
North Potomac
Germantown
Urbana
Kent Village
(If you don’t see your area listed, we likely serve it — just ask.)
Do I need a permit to build a deck in Gaithersburg, MD? Yes. For most decks and outdoor structures, especially composite or sizable wood decks, Montgomery County requires permits and inspections. Nevins Construction handles that for you.
What deck material lasts best in Gaithersburg’s climate? Composite or PVC (like Azek) resist moisture, humidity, and UV damage. Wood/pressure-treated can look great, but will need regular maintenance.
How long before my deck build is finished? Typically 2–3 weeks after permits are approved — design + quote, permitting, construction. Some premium/custom builds may take longer.
Can you design features like built-in lighting or custom railings? Absolutely. We offer built-in lighting, aluminum/composite railings, hidden fasteners — whatever fits your vision.
What about winter builds or snow load? We design all decks to meet or exceed local code requirements for snow load. If timeline or weather is a concern, we’ll plan accordingly.
