CWS Home Additions & ADU: The Orlando Owner’s Guide
CWS home additions and ADU projects in Orlando typically run $45,000 to $130,000 installed, depending on square footage, foundation type, and whether we’re building up or out. Most homeowners reach out to us after living with a space that no longer works: a garage that’s become storage overflow, a family room that’s too small, or a mother-in-law who needs her own entrance and kitchenette. The part that fails here isn’t a spring or a gasket. It’s the original floor plan. And that’s a bigger fix than any single component.
We’re Mason Remodeling Co Orlando, an independent contractor. We’re not affiliated with CWS, but we’ve built additions and ADUs across Orlando for years, and we handle the full scope: permits, foundation, framing, roofing, electrical, plumbing, drywall, and finish work. When you call, a live person answers. You’ll get a written price before any work starts. And you’ll know the name and photo of every crew member before they show up at your door.
Which CWS Models This Applies To
CWS, or Custom Wholesale Supply, doesn’t manufacture a single standardized home addition kit. What CWS provides is the materials backbone: engineered lumber packages, truss systems, and specification-grade components that many Orlando builders use for additions and accessory dwelling units. The compatibility question isn’t about matching a model number. It’s about matching the structural load path, the existing roof pitch, and the foundation type to the material package your addition requires.
Here’s the checkable detail most pages won’t tell you: an addition tied into an existing block home in Orlando needs a different ledger attachment and moisture barrier than an addition on a wood-frame house. Central Florida’s humidity and afternoon thunderstorms mean the flashing detail at the roofline intersection is the difference between a room that stays dry for 20 years and one that leaks by the second summer. We spec that joint for Florida conditions, not for a dry climate. If you have the original CWS delivery ticket or lumber package invoice, we can cross-reference the truss engineering and material grades to match new work to the existing structure. OEM structural lumber versus generic big-box lumber is a real decision for additions. The CWS-sourced material usually carries a grade stamp that a structural engineer has already signed off on for wind loads up to 150 mph. That matters in Orlando. A lot.
Styles & brands we work with
Signs Your CWS Home Addition or ADU Is Failing
- Cracks running diagonally from window corners or door headers. This usually means differential settlement or an undersized header. In Orlando’s sandy loam, slabs can shift after a wet season. We check the foundation before we frame anything new.
- A visible gap between the addition and the original structure. If the roof or wall has separated even a quarter inch, the tie-in wasn’t done properly. Water gets in through that gap, and the fix involves opening the wall.
- Musty odor or mold streaking on the ceiling of the addition. Florida’s dew point sits in the 70s for most of the year. A poorly flashed roof intersection or missing vapor barrier shows itself fast. This is a moisture intrusion problem, not just a smell.
- Doors that stick or won’t latch in the added space. The humidity cycle in Orlando makes wood swell and shrink. If the framing wasn’t dried to spec or the slab wasn’t level, you’ll feel it in the doors first.
- Electrical flicker when the ADU’s HVAC kicks on. An undersized subpanel or a shared circuit with the main house is a code violation and a fire safety issue. We pull permits and correct this when we renovate.

AfterReplacement Cost & What’s Included
For a home addition in Orlando, you’re looking at $45,000 to $130,000. A garage conversion runs $30,000 to $80,000, and a full ADU with its own kitchen and bath lands between $90,000 and $220,000. What drives the range is footage, foundation work, roof complexity, and whether the addition needs its own HVAC system or can tie into the existing one.
Every project gets a written price before we start. That price includes all labor, materials, permits, and cleanup. It does not grow at the end. The written guarantee covers our workmanship for 365 days from the completion date, with clear terms on what’s included and what isn’t. If a repair or installation fails within that year, we return at no charge. No dispute process. Call (850) 920-7745 and we’ll come back.
DIY or Call Us?
You can safely check the fundamentals: look for cracks, check for water staining, note where doors bind, and confirm the electrical panel isn’t tripping. But additions and ADUs are not DIY territory. The structural connections, the roof tie-in, the foundation tie, and the electrical service all require a licensed contractor and permits. In Orlando, unpermitted additions cause trouble when you go to sell, and insurance won’t cover a faulty structural repair.
Framing over a bad foundation is how you spend $45,000 twice. If the addition is pulling away, if there’s mold, if you can see sky through a seam, call us before you call a drywall guy. Tell me what the problem is. We’ll figure out the rest from there. (850) 920-7745.
FAQs
A properly built addition in Orlando lasts 50-plus years, but the first real test comes within three to five years when the roof flashing, window seals, and slab joints face repeated wet-dry cycles. Homes with a proper tie-in detail and hurricane-rated materials hold up. Homes flashed for a dry climate don’t. Most failures we see in Orlando are water intrusion at the roofline or slab settling. Call (850) 920-7745 if you’re seeing either.
Yes, in most cases we repair the failing component rather than rebuilding the whole space. If it’s a roofline leak, we open the affected section and reflash. If it’s slab settlement, we stabilize and level. If it’s a structural tie-in failure, we correct the connection and re-sheet. The fix is specific to what’s broken. Call us for an exact assessment; estimates are free.
A bathroom addition takes six to ten weeks. A full ADU with kitchen, bath, and separate entrance runs three to six months depending on permitting and inspections. We’ll give you a written timeline before we start, and we won’t disappear mid-project. If the work isn’t right within 365 days, we come back at no charge.
We don’t stock CWS-specific lumber packages on a shelf. What we do stock is the specification-grade materials we use across every project: KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, Kohler and Moen fixtures. We order structural lumber and trusses per project from CWS-compatible supply channels once your plans are approved. That means no compromise on grade or wind rating.
