Therma-Tru Driveway & Pavers Nationwide

Therma-Tru Driveway & Pavers: The Sunnyvale Owner’s Guide

Therma-Tru doesn’t manufacture driveway pavers or hardscape materials directly; the brand is best known for entry systems, but many Sunnyvale homeowners encounter “Therma-Tru” in the context of coordinated exterior packages where pavers, borders, and entry landings were specified by a single builder or remodel contractor. We stock and install compatible paver systems, entry landing replacements, and border restoration that matches these original specifications. Most Therma-Tru-coordinated paver repairs in Sunnyvale run $2,500-$7,500 for partial landing or border work, with full driveway paver installations ranging $7,000-$18,000. We carry common 60mm and 80mm paver thicknesses, matching border profiles, and permeable base materials on our trucks.

Homeowners usually discover the failure after rain: water pooling where the landing meets the threshold, settling that throws the entry door swing, or weed growth through joints that were supposed to stay tight. In older Sunnyvale tracts near Lakewood Village, we’ve seen original builder-grade sand-set pavers shift after fifteen years of clay soil expansion and contraction.

Which Therma-Tru Specifications This Applies To

If your home was built or remodeled between 2005 and 2018 with a “Therma-Tru package,” the paver specification was likely subcontracted to Belgard, Pavestone, or a regional equivalent, with Therma-Tru handling the entry door and coordinating the landing dimensions. The critical identifier is the landing depth: Therma-Tru entry systems typically require a 48-inch or 60-inch deep landing to maintain warranty clearance for door swing and threshold drainage. We’ve found original specs in Sunnyvale where the builder cheated this to 42 inches, which voids the door warranty and causes premature paver failure at the threshold.

To identify your part needs, measure the paver thickness (lift one edge if loose), note the border profile (soldier course, sailor course, or bullnose cap), and check whether the base is open-graded permeable or traditional compacted aggregate. We source OEM-equivalent pavers through our fifty-plus vetted brands, including Belgard and Techo-Bloc, and can match most discontinued profiles. Aftermarket equivalents save 15-25% on material but require verification that the compressive strength meets the original spec; we test this in writing before quoting.

Signs Your Therma-Tru-Coordinated Paver System Is Failing

• Water pooling at the entry threshold. The paver landing has settled below the door threshold, breaking the drainage plane. In Sunnyvale’s winter storm pattern, this backflows against the door jamb and rots the sill plate. We check the weep screed, the metal flashing that lets water escape, before we reset a single paver.
• Individual pavers rocking underfoot. The bedding sand has washed out or the base has degraded. Clay soils in the Washington Park area expand when wet and shrink in dry summers, creating voids beneath the bedding layer. Rocking pavers crack within two seasons if left unaddressed.
• Weeds or moss thriving in joints. Polymeric sand failure lets organic matter accumulate. Once roots establish, they wedge pavers apart and accelerate settling. Moss indicates chronic moisture, which in Sunnyvale usually means a drainage design flaw, not just maintenance neglect.
• The entry door scrapes or binds. Paver settlement has thrown the landing out of level, changing the door’s swing geometry. This is structural, not cosmetic; continued operation stresses the door hinges and the Therma-Tru frame, voiding any remaining warranty coverage.
• Chalky white efflorescence on paver faces. Soluble salts are migrating through the paver body, a sign of moisture trapped in the base or subgrade. In new construction this cures out; after five years, it signals a failed vapor barrier or improper base drainage that will eventually spall the paver surface.

Replacement Cost & What’s Included

What drives the range: paver material cost varies from $4/sf for basic concrete units to $14/sf for porcelain or natural stone; base depth depends on vehicle load (4 inches for foot traffic, 8-10 inches for driveway); and access affects excavation labor. Under Clause 1 of the Haven Standard, we deliver a written line-item quote before any work starts: material costs, labor hours, equipment rental, and permit fees listed separately. Our 365-Day Done Right Promise covers the installation; manufacturer defects in the pavers themselves are handled through the supplier. No change proceeds without a signed change order, which is why our projects finish within a few percent of the agreed number.

DIY or Call Us?

What you can safely check: lift a loose paver and photograph the base layer; note whether you see compacted gravel, sand, or mud. Measure the depth from paver bottom to native soil. Clear debris from weep screeds and verify that water runs away from the threshold, not toward it. These observations help us scope the job before we arrive.

Where DIY goes wrong: paver repair looks simple but requires plate compaction in lifts, precise slope calculation (1/4 inch per foot minimum away from structure), and edge restraint anchoring that most rental equipment can’t achieve. Resetting pavers without addressing the base failure guarantees recurrence within a season. The real risk is threshold damage: improper landing height relative to the door sill traps moisture and voids the Therma-Tru warranty. We document the existing condition with photos before we start, install to manufacturer clearance specs, and deliver the photo record with the final invoice.
