Boral Home Additions & ADU: The Orlando Owner’s Guide
Home additions and ADUs built with Boral materials in Orlando typically cost between $45,000 and $130,000 installed, depending on square footage, foundation work, and whether you’re adding a bedroom suite or a full accessory dwelling unit with its own kitchen and bath. Most Orlando homeowners call us when a Boral product has failed or needs matching, which usually means a cracked trim board, a warped siding panel, a failed window flashing detail, or water intrusion at a seam that’s been quietly getting worse through two Florida summers. We stock and install Boral-compatible materials, match existing profiles, and handle the repair or the full addition, and we’ll give you the real number before any work starts.
Here’s what you need to know up front: Mason Remodeling Co Orlando is an independent contractor, not affiliated with Boral. We work with Boral products every week, we know which profiles are still manufactured and which ones aren’t, and we’ll tell you straight if a repair makes sense or if replacement is the only honest answer. Tell me what the problem is. We’ll figure out the rest from there.
Which Boral Models This Applies To
Boral makes a range of building products used in Orlando home additions and ADUs, and the compatibility question is almost always about matching the exact product line and profile. The most common lines we work with are Boral TruExterior trim and siding, Boral Versetta Stone, and Boral cultured stone veneer. TruExterior trim comes in specific profiles: 5/4, 1x, and 2x, plus pre-milled shapes like corner boards, fascia, and window surrounds. Versetta Stone ships in two formats, tight set and dry stacked, and the color runs differ enough that matching an existing wall means getting the run lot number when possible.
The OEM-vs-aftermarket decision for Boral products is simpler than for most brands because Boral’s polymer-based TruExterior has no true aftermarket equivalent that matches in density and paint retention. Aftermarket PVC trims exist, but they expand and contract differently in Orlando’s heat and humidity, and the paint line between an old Boral board and a new generic board will show through within two seasons. When a client asks us to match something, we pull the profile, check the board width, and where possible get the lot stamp from the back of the old piece. That’s the difference between a repair you can’t see and one you’ll stare at every time you pull into the driveway.

Signs Your Boral Home Additions & ADU Is Failing
- Paint peeling at board ends or seams. Boral TruExterior holds paint better than wood, but water still gets behind it if the flashing was installed wrong or the caulk line failed. The paint failure is usually the symptom, not the disease.
- Swelling or softness at the bottom edge of siding or trim. Even polymer products fail when they sit in standing water. In Orlando, sprinkler overspray hitting a Boral board every morning for three years will do what rain can’t.
- Gaps opening at corner boards or window surrounds. Florida heat cycles cause thermal movement. If the installer used the wrong fastener or no expansion allowance, the boards separate and water follows.
- Stone veneer pieces cracking or falling off the wall. Versetta Stone and cultured stone fail more often from bad substrate prep than from product defects. In Orlando, the freeze-thaw cycle is rare but the humidity-driven corrosion of metal lath is real.
- Interior moisture stains near the roofline or at floor level where an addition meets the original house. That juncture is the highest-risk detail on any home addition. A failed Boral siding seam above that line means water is traveling down inside the wall, and by the time you see the stain, the repair is no longer a trim swap.

AfterReplacement Cost & What’s Included
In Orlando, a Boral trim or siding repair on a home addition or ADU runs roughly $400 to $1,800, which matches our standard roof repair and repair-style pricing for a crew to remove the failed piece, inspect what’s behind it, replace flashing or substrate if needed, and install a new Boral-compatible piece matched to your profile. A larger section repair, like an entire gable end or a complete window surround rebuild, lands in the $1,800 to $4,500 range when we’re pulling off cladding, checking framing, and re-flashing the opening. Full additions and ADUs are a different animal: $45,000 to $130,000 for the addition, and if you’re building a standalone accessory dwelling unit with plumbing and power, that’s $90,000 to $220,000, with garage conversions running $30,000 to $80,000 if you already have the shell.
What’s included on every repair or build: a written price before any work starts, line-item parts and labor, the Threshold Standard crew verification where every team member is background-checked, identity-verified, and introduced to you by name and photo before they arrive in a clean marked uniform with a photo ID badge at your door, and our 365-Day Done Right Promise, which covers the work for 365 days from the completion date and means any repair or installation failure gets fixed at no charge.
DIY or Call Us?
There are things you can safely check yourself, and things that go wrong fast. You can look for gaps in caulk lines, inspect bottom edges for sprinkler damage, and check that downspouts aren’t pouring water directly onto a Boral trim board. What you shouldn’t do is pull off a failed piece to "see what’s behind it." Once the cladding comes off and you find rotted framing, a bad connection between the addition and the original roofline, or exposed wiring from the original ADU build, you’ve turned a trim job into a structural problem that needs a permit and a crew. We’ve opened enough Orlando additions to know that what looks like a one-hour fix on the outside is often hiding the real issue behind the wall. Call (850) 920-7745 and we’ll put eyes on it before you take anything apart. Estimates are free.
FAQs
Boral TruExterior trim and siding, properly installed and painted, typically lasts 20 to 30 years before needing major attention in Orlando’s climate. The failure point is almost always the flashing and caulk joints, not the board itself, which is why we warranty our installations for 365 days and recommend an annual visual check of seams and bottom edges. Call (850) 920-7745 and we’ll take a look at yours.
In most cases, yes, a single failed trim board or a short run of siding can be removed and replaced without touching the rest of the addition, provided we can match the profile and color. A repair only makes sense if the substrate behind it is sound and the water intrusion hasn’t traveled. If the framing has rotted or the flashing detail was wrong from the start, patchwork becomes more expensive than a proper section replacement. We’ll tell you which one you’re looking at after an inspection. Call (850) 920-7745 to schedule the estimate.
A standard single-board trim replacement on an Orlando home addition usually takes half a day to a full day, including removing the old piece, inspecting behind it, and installing and painting the new material. A full gable end or window surround rebuild can run two to three days depending on what’s behind the cladding. We’ll give you a written schedule with the written price before any work begins. Call (850) 920-7745 and we’ll scope the job.
We keep common Boral TruExterior profiles, standard trim sizes, and a selection of Versetta Stone colors in our Orlando inventory, and our crews carry the most-used items on the truck for repair calls. For odd profiles, discontinued colors, or large-format stone pieces that aren’t in local supply yards, we order direct and usually have materials in hand within a few days. During your estimate, we’ll match the specific part and let you know if it’s on the truck or in the order queue before we schedule the work. Call (850) 920-7745 to check your profile.
