Belgard Home Additions & ADU: The Sacramento Owner’s Guide
If you’re planning a Belgard home addition or ADU in Sacramento, you’re looking at an installed range of $45,000 to $130,000 for an addition, and $90,000 to $220,000 for a full ADU construction. That’s the honest number, and we’re not going to dance around it. The bigger question is whether your Belgard hardscaping integrates cleanly with the new structure, because the patio, walkway, or retaining wall you installed five years ago doesn’t just sit there while foundation work happens around it.
Most Sacramento homeowners discover this the hard way: the addition is framed, the concrete is poured, and then someone notices the Belgard pavers near the new foundation have shifted, cracked, or sunk. The issue is almost always substrate failure beneath the pavers, not the Belgard product itself. Sacramento’s clay-heavy soil expands and contracts with our wet winters and dry summers, and once you disturb the ground for an addition, that movement gets worse before it settles. We see it regularly in Land Park, East Sacramento, and Citrus Heights, where homes from the 1950s and 60s sit on soil that has never stopped moving.
Bradford Remodeling Co Sacramento is an independent contractor, not affiliated with Belgard. We install Belgard products and we build additions and ADUs that tie into existing Belgard hardscaping without compromising either one.
Which Belgard Models This Applies To
Belgard’s hardscape lines break into three broad families: their paver series (Catalina, Mega-Arbel, Urbana), their wall blocks (Dublin, BelAir, Diamond), and their permeable pavers (Aqua-Bric, Eco-Dublin). The compatibility issue with additions and ADUs isn’t about the paver style, it’s about what’s underneath. If your existing patio or walkway was installed with a proper 6- to 8-inch compacted aggregate base and a 1-inch sand setting bed, it usually survives an addition. If it was installed with 2 inches of sand over native soil, which is distressingly common in Sacramento tract homes built before 2000, you’ll get movement.
How to identify what you have: pull up one edge paver where the new foundation will meet the old hardscape. If you see crushed rock under the sand, the base was done right. If you see dirt, it wasn’t. That one observation tells us whether we can save the existing Belgard work or whether we’re redoing a section of it. For OEM versus aftermarket: Belgard pavers are color-blended at the factory, and a paver from a different production run will not match, even with the same style name. When we tie an addition into existing Belgard work, we recommend sourcing replacement pavers from the same manufacturer and, where possible, the same batch number, because Sacramento sun fades everything, and a one-year-old paver next to a ten-year-old paver will show it.

Signs Your Belgard Home Additions & ADU Is Failing
- Pavers sinking near the foundation line. This almost always means the substrate was never compacted to spec or water is now pooling against the new foundation and washing fines out of the base. Once water gets under the bedding sand, it finds the soft spots, and the pavers follow.
- Gaps opening between pavers and the new slab. Sacramento’s clay soil shrinks in summer. A 3/8-inch gap in August may close by February, but if it stays open through the rainy season, the edge restraint has failed, and the whole field can start walking outward.
- Standing water on the patio after a rain. Belgian block doesn’t fail, but pitch does. An addition changes the roofline, and suddenly your downspout is dumping water onto a patio that used to drain fine. Water that sits on Belgard pavers for days is water that’s working its way underneath them.
- Cracked pavers along the seam where old hardscape meets new foundation. This is settlement, plain and simple. The new footing is still compacting, and the adjacent pavers are taking the flex. A cracked paver at the seam means the base under that section was already marginal.
- Weeds or grass pushing up through paver joints. That’s a sign the joint sand has washed out, which means water is getting through, which means the base is eroding. It starts as a cosmetic annoyance and ends as a patio that needs to be pulled up and reset.

AfterReplacement Cost & What’s Included
Here’s what we quote in Sacramento, and these are real numbers from our written estimates:
- Full home addition (400-800 sq ft): $45,000 – $130,000
- ADU construction (garage conversion or new build): $90,000 – $220,000
- Garage conversion specifically: $30,000 – $80,000
What drives the range is scope: a 400-square-foot bump-out with basic finishes lands at the bottom. A full ADU with a kitchen, bath, and separate meter lands at the top. When Belgard hardscaping is part of the job, the paver work is budgeted separately, usually $3,500 to $11,000 for a patio, depending on square footage and whether we’re tying into existing pavers or starting fresh.
Every estimate includes a written line-item scope, the materials list with manufacturer names, and our 365-Day Done Right Promise in writing. If the paving or the addition work fails within a year, we come back and correct it at no charge. That’s not marketing language. That’s the guarantee we hand you at job close, signed.
DIY or Call Us?
You can check the edge of your existing Belgard patio against a new slab and tell us what you see. You can watch where water pools after a rain and mark it with a paver chalk. That information helps us estimate faster. What you shouldn’t do is pull up Belgard pavers and try to re-base them yourself around a fresh foundation. The substrate work requires compaction equipment, a proper aggregate lift schedule, and an eye for what Sacramento clay does when you add water. Get the base wrong and the pavers settle again in one winter.

FAQs
Belgard pavers themselves are concrete units rated for 50+ years of freeze-thaw cycles, and Sacramento’s climate is mild on the paver itself. The weak link is the base. A correctly installed aggregate base under Belgard pavers in Sacramento will hold for 20 to 25 years before it needs re-leveling, and then only if drainage has been fighting it. Poorly installed bases fail in 3 to 5 years. The paver isn’t the problem; the prep is.
If the pavers are sinking in a defined area, we can often pull that section, correct the base, and reset the same pavers. What we can’t do is make a color-matched repair look invisible if the pavers have been in Sacramento sun for a decade; the replacement batch will read as newer. For that reason, when an addition is going in, we sometimes recommend relocating salvaged pavers to the visible area and putting the new batch where the eye doesn’t land first. Call (279) 226-1509 and we’ll walk you through the options on your specific patio.
A standard home addition runs 10 to 16 weeks from permit to final inspection. An ADU runs 16 to 24 weeks, depending on utility connections and whether you’re converting a garage or building new. Sacramento County plan check and permits add time that no contractor can compress, and we don’t promise unrealistic schedules. We give you a written timeline, and we tell you when it changes.
We don’t warehouse pavers on a truck; nobody in Sacramento does. We order directly from Belgard’s Sacramento distribution network, which lets us match series, color, and batch where available. We also specify Belgard alongside brands like KraftMaid, Cambria, and Silestone when the addition scope includes kitchen or bath surfaces, so the material list is documented from day one. Estimates are free; call (279) 226-1509 and we’ll price your project with the actual materials written into the scope.
Straight scope, firm price, no surprises after the drywall goes up. If you’re planning a Belgard home addition or ADU in Sacramento, call (279) 226-1509 for a free, written estimate. We’ll walk the site, look at the existing hardscape, and give you a number that holds.
