Cambridge Pavers Home Additions & ADU Nationwide

Cambridge Pavers Home Additions & ADU: The Long Beach Owner’s Guide

If you’re planning a home addition or ADU in Long Beach with Cambridge Pavers as part of the exterior hardscape or foundation-to-patio transition, the installed project typically runs $45,000 – $130,000 depending on square footage, foundation work, and paver scope. We stock Cambridge-compatible paver lines on the truck for additions and ADU projects in Long Beach, so we can show you actual samples before the written price is finalized. Most owners figure out they have a paver or paver-adjacent issue after a rain season or during a foundation inspection, when the existing patio or walkway no longer sits flush against the new addition’s slab edge. That gap, or a set of sunken pavers near the addition’s drip line, is exactly what this page addresses.

Which Cambridge Pavers Models This Applies To

Cambridge Pavers makes several paver lines that show up on Long Beach home additions and ADU projects. The most common ones we see are the Ledgestone and Roundtable collections for patios, and the Maytrx or Sherwood lines for walkways and driveway aprons that tie into a new addition’s entry. Identifying your specific paver matters because Cambridge’s dimensional ranges run from 60mm to 80mm thickness for vehicular areas, and 40mm to 60mm for pedestrian patios and walkways. That thickness difference is exactly why you cannot swap a pedestrian paver from an old patio for a driveway-rated paver without creating a slope or drainage failure. Cambridge also has a specific “Blu 60” series with a denser concrete mix used in coastal applications, and Long Beach’s marine air is one place we recommend it over the standard 60mm line if the paver will face salt humidity daily. When matching an existing Cambridge paver to a new addition, we check the underside markings and edge profile, not just the surface color. Aftermarket equivalents do exist, but Cambridge’s color blending and edge spacing are the tightest in their class, and pairing a mismatched aftermarket paver against an existing Cambridge field creates a visible seam within 12 months of Long Beach sun exposure.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing

• Pavers near the addition’s foundation edge are sinking or tilting. This usually means the original sand and base layer was not compacted for the new structure’s drainage pattern, and water is pooling against the addition’s slab edge in Long Beach’s clay-heavy soil zones like Bixby Knolls.
• A visible gap opens between the new addition’s slab and the first paver row. In Long Beach’s wet winters, this gap becomes a channel for runoff to undermine the paver base, and it only widens as soil expands and contracts through the year.
• Efflorescence, or a white chalky film, forms on pavers near the addition’s roofline. This is mineral salt pushing through the paver surface, common in Long Beach’s coastal humidity, and it signals that the paver’s sealer has worn off near the addition’s drip line.
• Paver edges along walkways or steps feel loose underfoot. The edge restraint has failed or never had a concrete haunch installed, and the paver will keep moving until the restraint is restored. This is also a trip hazard for kids and pets.
• Pooling water sits on pavers for more than 24 hours after rain near the ADU’s entry. That means the original slope toward a drain or yard edge has settled out of spec, and in Long Beach’s rainy February stretch, it will find its way under the addition’s door threshold eventually.

Replacement Cost & What’s Included

For a Cambridge Pavers home addition or ADU in Long Beach, the full project range is $45,000 – $130,000. That range includes plans and permits, foundation and framing, electrical and plumbing rough-in, Cambridge paver installation for patios or walkways tied to the addition, and interior finishes. Where Cambridge pavers are an add-on to an existing addition, a paver patio installation in Long Beach runs $3,500 – $11,000, and a driveway apron or walkway can run $7,000 – $18,000 depending on square footage. We break out the paver portion separately on the written scope of work, so you see the paver materials, base prep, edge restraint, and sealing as line items before you approve anything. Every Cambridge paver project we install in Long Beach carries our 365-Day Done Right Promise: if the pavers shift, settle, or show color inconsistency within the first year, we come back and make it right.

DIY or Call Us?

There are a few checks you can do yourself before calling us. Look at whether the pavers near your addition are flush with the foundation edge, whether water pools after rain, and whether any pavers wobble under a foot press. What you should not do is pull up pavers, regrade, or compact a new base yourself, especially near a new addition’s foundation or ADU slab. Undercutting a foundation-adjacent paver bed in Long Beach’s expansive clay soil without proper compaction and drainage planning can direct water toward the structure, not away from it. Graham Stein has spent well over a decade watching well-meaning homeowners turn a $3,000 paver fix into a $20,000 drainage and foundation problem. If you’re unsure, call (562) 512-7086 and we will walk through what you’re seeing before you lift a single paver.
