Signs You Need Deck Work in Rockville, MD
Decks rarely fail all at once. They give you warnings for a season or two before they do.
Boards that feel soft or spongy
If a screwdriver pushes into the board without much effort, the wood is rotting from the inside out.
A railing that moves when you lean on it
Loose posts and sagging rails are the most common deck safety failure we find on older builds.
The ledger is pulling away from the house
Rust stains or a visible gap where the deck meets the house means the attachment needs to be opened up and inspected.
You want composite instead of yearly staining
Homeowners switching to capped composite are usually done with sanding, sealing and re-staining every other year.
A hot tub, pergola or screen room is going in
Added weight and added roof load have to be designed into the frame, not retrofitted onto it.
The Deck Services We Offer in Rockville
One crew handles the deck and everything attached to it, so you are not coordinating three trades on one project.
Deck replacement and rebuilds
When the frame is sound we re-deck it. When it is not, we tell you which parts actually have to come out instead of quoting a full tear-down you do not need.
Railing, stairs and lighting
Cable, glass panel, aluminum baluster and traditional wood railing systems, plus code-compliant stairs and low-voltage deck lighting wired during the build.
Porches, pergolas and covered structures
Covered porches, pergolas, built-in seating and planters designed as part of the same plan so the structure carries the load it is supposed to.

Client Reviews
Why Rockville, MD Trusts Us for Custom Decks & Porches
J&J Pro Build built our composite deck and pergola in Columbia and I could not be more impressed. The crew was professional, on time, and the quality is outstanding. They handled everything, permits, inspections, cleanup. Highly recommend.

We had them install a cedar privacy fence around our entire property in Ellicott City. Fast, clean work, perfectly straight lines, and they were very knowledgeable about HOA requirements. Will use them again for our patio project.

J&J replaced the siding on our entire home in Bethesda with James Hardie. They discovered some moisture damage behind the old siding and repaired it before re-siding. That kind of thoroughness is rare. The house looks brand new.
