Wood and composite deck repairs across Maryland.
"Added a deck extension with stairs and a large cement pad. Workers showed up on time, matched existing deck and were professional. CBJ listened to our needs and made sure we were happy with the work before closing the job. We are happy with the results and I would recommend this company to friends looking for exterior work done."
Undercarriages 90% of the time are either wood or wood covered in some type of covering. Whether your deck surface is composite or lumber, what's holding it up is almost always wood.
The number one cause for people calling us about their deck repairs is wood rot. Rot can be very dangerous in the structural areas of your deck because it can cause collapse. Rotted joists, shifting posts, a failing ledger board — these aren't cosmetic problems. They're safety problems.
CBJ handles undercarriage repairs for both wood and composite decks across Baltimore County, Harford County, and the surrounding areas. Structural repairs can involve post replacement, header replacement, deck joist replacement, or a footer replacement. We get underneath, find the problem, and fix it right.
Get Your Project StartedWood can't last forever. Eventually, you will have to repair your wood deck. Unless a tree fell on it or lightning struck it, it's almost always wood rot that's causing you problems.
A lot of companies are not willing to reuse the undercarriage — or not skilled enough to salvage it. If wood rot has only spread to the decking and railings, there's still a good chance that you only need to replace the decking and railings and not the entire undercarriage. That can save you thousands upon thousands.
Our services include, but are not limited to:
Is your composite decking fading from the sun? Has it cracked or splintered? Have the vinyl handrails broken? We can help you with that.
Matching the material can be extremely difficult depending on how many years it's been since your deck was installed. Vinyl and composite companies consistently change out fasteners, hardware, and slight design choices on their railing pieces — so you can almost never get a perfect match. The older the railing, the harder it is to match, and sometimes a full replacement is the only option.
CBJ will try to help you avoid that by using our suppliers. If a match isn't possible, we'll give you as close to a repair solution as we can — and if it comes to replacing your railing or decking entirely, we'll help you through that too.

Common questions about building a deck in Baltimore. Still have more — just call or send us a message.
Most decks are built in 1–2 weeks once permits are approved. Larger or multi-level decks may take 2–3 weeks. Permit approval timelines vary by jurisdiction in Baltimore County.
Yes. We're responsible for many of the decks across the Baltimore skyline. Bring one of our experts out and they'll tell you what we need to do.
Yes, most decks require a building permit in Baltimore City and Baltimore County. CBJ Home Improvement handles all permit applications so you don't have to worry about it.
No — as long as the dimensions of the deck are maintained and there is no major structural work being done, a repair does not require a permit in Maryland. Replacing boards, railings, and surface-level components is considered maintenance, not new construction.
It varies. We've done decking projects from $6,000 to over $90,000. There are many factors at play, from the types of materials in your deck to the scope of the project. The best way to get a real number is to have us come out and take a look.
No. Power washing forces water deep into the wood fibers, which causes swelling, splintering, and accelerates rot. It also strips the stain and damages the surface of the boards. If your deck needs cleaning, a gentle wash with the right cleaner is the way to go — not a pressure washer.
Yes. We handle the entire permitting process for you. The cost will vary depending on the complexity of the permit process for your specific project, but we take care of all the paperwork and applications so you don't have to.
