What we look for
Six structural checkpoints on every deck visit
A deck can look fine on the surface and still be unsafe underneath. These are the six things we inspect before we recommend a repair, a resurface, or a rebuild.
Footings & frost heave
Connecticut footings should bear below the ~42-inch frost line. Sinking or heaving posts telegraph into bouncy floors and racked frames, so we confirm depth and bearing.
Joist span & spacing
Composite decking needs solid, correctly-spaced support (often 12"–16" on center). We verify the framing can carry the surface you want before we ever quote a resurface.
Flashing & water management
Trapped water rots frames from the inside out. We trace how the deck sheds water at the house, the beam, and the posts — the detail that decides how long a rebuild lasts.
Railing & guard code
Guards are generally required where the deck is more than 30" off grade, at a height and load the code expects. We assess baluster spacing, post anchorage, and rigidity.
Stairs & stringers
Uneven risers and notched stringers are both a safety issue and a code one. We measure rise, run, and headroom so new stairs are consistent, sturdy, and comfortable.
Materials, honestly

How It Works
Kennedy Home Services makes it simple — four steps to a finished project.
01
Build it & tell us about it
Start with the deck builder at the top — drag the size, pick a shape and color, and watch it take form. Then answer a few questions on timing and access. Together they build your planning profile.
02
Upload photos
Add clear photos of the structure, the ledger, stairs, and railings. A real person on our team reviews every one — no auto-diagnosis.
03
Get three planning options
We turn your details into a three-option proposal with planning investment ranges, so you can compare approaches side by side.
04
On-site measure & inspection
We confirm the structure, take field measurements, and check the six checkpoints above. This is where planning numbers become exact.
05
Selections & permits
Choose decking, railings, and finishes from real samples. We coordinate permits with your town when the scope requires them.
06
Build & walkthrough
Our crews build to plan, protect your property, and close out with a final walkthrough so the finished deck is exactly what we agreed.
Part of the system
The deck builder is not a gimmick. It's the front door to the estimating engine.
The same interactive builder you used at the top of this page is wired into how we actually work. What you shape on screen — size, shape, color, railings, stairs, lighting — flows straight into the estimating engine, which turns it into the three-option planning proposal you can compare in the portal. No napkin sketch, no guesswork meeting: you see the deck before we price it, and the price follows what you built.
You build it in the browser
Drag the dimensions, choose a shape, recolor the planks. The 3D preview updates live — that model is your planning profile.
It feeds the estimating engine
Your inputs drive the same governed engine the office uses — material planning, labor, disposal, and margin guardrails in integer cents.
Out comes a three-option proposal
Surface, complete, or rebuild — each with a planning range, scope, and payment schedule, ready for your on-site review.

Direct answers
Deck questions, answered straight
Clear answers help you decide whether the next step is a fit. Project-specific facts are confirmed during review and documented before work begins.
Do I need a permit to build or replace a deck in Fairfield County?
It depends on your town and the scope of work. New decks, structural rebuilds, and changes to height or footings typically need a permit, while a like-for-like surface swap sometimes does not. Kennedy reviews your town's requirements and handles permit submissions when the project calls for them.
How deep do deck footings need to be in Connecticut?
Connecticut's frost line is generally around 42 inches, so footings are commonly sized to bear below that depth to resist frost heave. Exact depth and footing size depend on soil, deck height, and local code, which we confirm during the on-site inspection.
Should I repair, resurface, or fully rebuild my deck?
That comes down to the framing. If the posts, beams, and joists are sound and code-compliant, resurfacing is often the efficient path. If the ledger is failing, posts are sinking, or rot has reached the structure, a rebuild is usually safer and more durable long-term. We tell you which, honestly, after we look.
What is the difference between Trex Enhance, Select, and Transcend?
They are Trex decking lines that differ mainly in the thickness of the protective cap and the warranty length. Enhance carries a shorter fade/stain warranty, Select a longer one, and Transcend the longest with a deeper wood-grain texture. We bring physical samples so you can see and feel the difference in person.
Is composite decking worth more upfront than pressure-treated wood?
Composite costs more at the start but needs far less upkeep — no annual staining or sealing, just occasional cleaning. Pressure-treated wood is the lower-entry option but asks for regular maintenance to avoid splintering and rot. The better value depends on how long you plan to stay and how much upkeep you want.
Can you put composite decking over my existing wood frame?
Often, yes — this is deck resurfacing. The frame must first pass inspection: solid joists, correct spacing (frequently 12"–16" on center), and no rot. Composite boards need firm support, so we verify the framing before we quote a resurface rather than assuming it will work.
How long does a deck project take?
It varies with size and scope. A focused repair or resurface can take a handful of days; a full custom build with footings, framing, railings, and stairs typically runs longer. Height, access, weather, and permitting all factor in. We give you a working timeline before we start and keep you updated.
Does Kennedy handle the town inspections?
Yes. When your project requires a permit, we prepare the application, schedule the required inspections with your local building department, and stay on top of approvals so the work stays on the right side of code throughout.
Why does my deck bounce or feel spongy?
A bouncy deck usually points to joists that are undersized, over-spanned, or spaced too wide for the load — sometimes combined with fastener or framing fatigue. It is worth having inspected, because the fix ranges from added blocking or sistering to reframing depending on what we find underneath.
What causes a deck to pull away from the house?
The most common cause is a failing ledger connection — undersized or corroded fasteners, missing or incorrect flashing, or water damage at the house wall. A deck separating from the structure is a safety concern and should be inspected promptly. We check the ledger joint on every visit.
Are my railings up to code?
Guard requirements generally apply once a deck is more than about 30 inches off the ground, with rules on height, baluster spacing, and the load the rail must resist. Older railings are frequently too low or too loose. We measure and assess anchorage and rigidity during the inspection.
Can you add lighting to an existing deck?
Usually, yes. Low-voltage LED lighting can be integrated into stair treads, post caps, railings, and fascia on many existing decks. We plan the wiring route and transformer so the lighting is clean, safe, and usable after dark — a popular upgrade during a resurface.
What maintenance does a composite deck actually need?
Mostly cleaning. Rinse or wash the boards a couple of times a year, clear debris from between them, and avoid harsh chemicals or pressure settings the manufacturer does not recommend. There is no staining or sealing, which is the main reason people choose composite for low upkeep.
How do I know if my deck has rot?
Soft or spongy spots, dark staining, crumbling wood at the ledger or posts, and fasteners that pull out too easily are common signs. Rot often hides where water collects — the ledger, beam-to-post joints, and board ends. A hands-on inspection is the reliable way to know how far it has gone.
Will a new deck increase my home's value?
A well-built deck adds usable outdoor living space that many Fairfield County buyers value, and it can improve how the home shows. The exact return depends on your market, the quality of the build, and how it complements the property. We build for durability and resale appeal, not just the day we hand it over.
Do you build on sloped or uneven yards?
Yes. Sloped sites are common here and are handled with taller posts, stepped or tiered framing, and properly sized footings. A slope can also create opportunities — multi-level decks, built-in seating, or under-deck storage. We assess grading and drainage as part of the plan.
What should I photograph before requesting a deck estimate?
Capture the whole deck from each corner, the spot where it meets the house (the ledger), the stairs and railings, and a few shots of the framing underneath if you can reach it safely. Photos of any problem areas help our team prepare before the on-site visit.
Can I stay in my home during a deck build?
In nearly all cases, yes. Deck work happens outside, so you can stay home while we build. We protect the surrounding property, manage debris, and keep access clear. We will flag anything — like a temporary door or path change — before it affects your day.
What is the best material for a pool deck?
It comes down to heat, slip resistance, and maintenance. Lighter composite tones stay cooler underfoot, and textured surfaces help with wet traction near water. We weigh those factors against your budget and how the deck ties into the pool surround before recommending a direction.
Do composite decks get hot in the sun?
They can, especially darker tones in direct summer sun. Lighter colors and heat-mitigating lines run cooler. If your deck gets strong afternoon sun, we can factor color and orientation into the plan and bring samples so you can judge the feel for yourself.
How far apart should deck joists be?
Spacing depends on the decking material and the joist size. Many composite products call for 12" to 16" on center, while some wood decking can span wider. Getting this right prevents bounce and sagging, which is why we confirm span and spacing before resurfacing an existing frame.
Can you match or expand my existing deck?
Often we can extend an existing deck or tie a new section into it, provided the original structure is sound and the framing can be matched or reinforced. We assess the existing footings and frame first so the addition is level, sturdy, and integrated rather than a bolted-on afterthought.
What happens if you find hidden rot during the project?
We stop, show you the affected area, and explain the repair options with clear pricing before continuing. No surprise work gets approved on the spot — you decide how to proceed once you can see the condition for yourself. This is standard on any project where concealed conditions are possible.
