What We Build & Repair
Senco Home Services builds and repairs decks for homeowners across Tewksbury, MA and the surrounding towns — from a brand-new deck built from the footings up, to replacing decking that's had it, to fixing rotted boards and loose railings before they turn into a safety problem. As a licensed deck builder in Tewksbury, MA, we bring the same waterproofing and flashing discipline we use on every roof to the one part of a deck most contractors get wrong: where it meets the house.
New Deck Construction
Whether it's your first deck or a replacement for a layout that never quite worked, we build to Massachusetts code from the footings up — correct post spacing, joist sizing, and guardrail height, so the deck is as safe as it is good-looking. Get a free deck estimate and we'll walk the property with you before we price anything.
Deck Replacement
Old decking often outlives the structure underneath it, or the other way around — sun-bleached boards on a frame that's actually still sound, or newer boards nailed onto rotted joists. We check what's under the surface before recommending a full tear-off versus a resurface, so you're not paying to replace more than you need to.
Deck Repair — Boards, Railings & Rot
Not every deck problem needs a full rebuild. Cracked or split boards, a wobbly railing, soft spots near the stairs, or rot where a post meets the ground can usually be repaired directly. We check the framing underneath any damaged decking, since surface rot is often the first visible sign of a slower leak below.
Pressure-Treated Wood & Composite Decking
We build with both pressure-treated lumber and low-maintenance composite decking, and we'll walk you through the real trade-offs. Pressure-treated costs less up front but needs periodic staining and sealing to hold up over the years. Composite costs more but skips most of that yearly maintenance and resists rot, fading, and splintering. Either way, we'll spec what fits your budget and how much upkeep you actually want to do.
Permits & Code
Massachusetts building code requires a permit for most new decks and many replacements — footing depth, ledger attachment, and guardrail height (over 30 inches) all have to meet code. We pull the permit and handle the inspection process as part of every deck project, so you're not the one chasing down the town.
Ledger & Flashing — Where Most Decks Actually Fail
The single most common point of failure on a deck isn't the decking boards — it's the ledger board where the deck attaches to your house. Flash it wrong and water gets behind the siding and into the wall framing, sometimes for years before anyone notices. Senco is a roofing and waterproofing company first, so we flash a deck ledger the same way we flash a roof valley or chimney: properly lapped, sealed, and built to keep water moving away from the house, not into it.
Deck Replacement
Full tear-off and rebuild when the structure underneath has had it.
Deck Repair
Rotted boards, loose railings, and soft spots fixed at the source.
Composite & Pressure-Treated Decking
Both material options, priced and explained honestly up front.
Railings & Guardrails
Rebuilt or repaired to current code height and spacing.
Ledger Board & Flashing
Flashed with the same waterproofing discipline we use on every roof.
Deck work often turns up siding or trim that's due for attention near the ledger — we can look at that at the same time. See our siding services if you'd rather handle the whole exterior in one visit.
Why Homeowners Trust Senco
Deck work backed by a roofing company's eye for water
Anyone can nail down decking boards. Keeping water out from underneath is the harder part — and it's the part we've spent seven years mastering on roofs across Tewksbury and Billerica. We bring that same eye for flashing and drainage to every ledger board, post base, and stair stringer we build.
Backed by Senco — 10-Year Workmanship Warranty
Every deck we build or repair is backed in writing by Senco's own 10-Year Workmanship Warranty. Decking material — pressure-treated lumber or composite — carries its own separate manufacturer's warranty, and we'll walk you through exactly what's covered before work begins.

We had an excellent experience with Senco. Chris was amazing! He was professional, patient, explained things clearly and answered all our questions. He always returned our phone inquiries. He and his workers went above and beyond our expectations. His crew replaced our roof in one day. Clean up was great. We also had Senco remove the ice dams prior to having the roof replaced. Once again, Senco's pricing was fair, the crew was hard working and responsive to any concerns we may have had. I highly recommend this company and would use them again.Elaine Levine · Google Review
Senco did many homes in my neighborhood. I recognized their competence, honesty and quality right away and knew I had to have the Senco team on my roof too. Very satisfied with all aspects of the demolition and installation which was quite complex. Replaced facia boards with AZEK, new gutters, and a new roof. Thanks again Senco!! Excellent job!!Jim O. · Google Review
Owner, Chris, was extremely knowledgeable and very professional. He always responded promptly to our questions and we always felt we were important to him. His crew worked so great together, like they never had to ask each other for anything, they just knew what was next. The job was started earlier than planned and everything was done above and beyond what one would expect. We would, and have, already recommended Senco Home Services to other homeowners and look forward to having him back to replace our old windows. Thank you, Chris, for making this an easy decision for us and for providing quality workmanship. Stephen and Melissa Spinosa in BurlingtonJenna Spinosa · Google Review

Deck building & repair questions
How much does a new deck cost in Massachusetts?
It depends on size, framing height, and whether you choose pressure-treated lumber or composite decking — those two alone can shift the price significantly. We don't quote a number sight-unseen; we offer a free, no-obligation on-site estimate so you get an honest price for your actual deck, not a rough guess.
Pressure-treated wood or composite decking — which should I choose?
Pressure-treated costs less to install but needs periodic staining or sealing to hold up over the years. Composite decking costs more up front but skips most of that maintenance and resists rot, fading, and splintering. Neither is wrong — it comes down to your budget and how much upkeep you want to do. We'll lay out both options honestly during your estimate.
Do I need a permit to build a deck in Massachusetts?
In most cases, yes — Massachusetts building code requires a permit for new deck construction and many replacements, covering things like footing depth, ledger attachment, and guardrail height. We pull the permit and handle the inspection process as part of every deck project we build.
How do I know if my deck needs repair or a full replacement?
If the framing and posts underneath are still sound and it's mainly the decking boards, railings, or a few soft spots that need attention, a repair usually makes sense. If the structure itself is rotted, undersized, or was never built to current code, a full replacement is the safer call. We inspect underneath the surface before recommending either one.
Can you fix a deck that's leaking or rotting where it meets the house?
Yes — that's actually one of the most common deck problems we see, and it comes down to a poorly flashed ledger board where the deck attaches to your house. Water gets in behind the siding and rots the framing from the inside. Since we're a roofing and waterproofing company first, we flash a ledger the same way we flash a roof valley or chimney, and we can repair existing water damage at the same time.
Do you offer financing for deck projects?
Yes. Through our lending partner GreenSky, deck projects can be financed with 0% financing for 12 months (no interest, no payments), plus longer 10- and 15-year plans for bigger builds. The credit check is a soft pull and won't affect your score. See your financing options →
