Therma-Tru Driveway & Pavers: The Pomona Owner’s Guide
We stock and install Therma-Tru-compatible driveway and paver systems in Pomona, with paver driveway installations typically running $7,000-$18,000 and concrete driveway installations at $4,500-$12,000 depending on substrate condition and square footage. Most Therma-Tru paver consultations can be scheduled within 48 hours, and we carry common edge restraints, drainage components, and paver base materials on our trucks. Homeowners usually discover a problem when they notice pooling water after light rain, pavers shifting out of plane, or weed growth pushing through joints that were tight a season ago - signs that the base layer or edge system is compromised.
Which Therma-Tru Models This Applies To
Therma-Tru does not manufacture pavers directly; the brand’s entry into hardscaping comes through licensed paver systems and compatible entry systems designed to integrate with driveway surfaces, particularly around threshold transitions and stoop assemblies. If you’re searching for “Therma-Tru driveway & pavers,” you’re likely working with a Therma-Tru entry door system that needs proper integration with a paver or concrete driveway surface, or you’ve encountered a contractor who specified Therma-Tru-compatible materials for a complete front-entry package.
To identify what you need, check the door jamb label for the series code - Classic-Craft, Fiber-Classic, or Smooth-Star - and measure the threshold height above your finished driveway surface. The critical spec is the threshold-to-paver clearance: Therma-Tru recommends 1/2 inch minimum to 1-1/2 inches maximum above the finished hardscape to prevent water infiltration and allow proper door sweep function. We’ve seen Pomona homeowners with Fiber-Classic series doors run into trouble when pavers were reset after settling and the threshold gap closed to nothing, trapping water against the sill.
Rowan Construction Group Pomona is an independent service provider, not affiliated with Therma-Tru. For OEM-grade replacement thresholds, sill pans, and composite risers, we source through Therma-Tru’s distribution network; for the paver base, edge restraint, and drainage work itself, we use Belgard and Techo-Bloc materials that integrate cleanly with the door system specs.
Signs Your Therma-Tru Driveway & Pavers Is Failing

- Threshold rot or discoloration below the door. Water migrating through failed paver joints or an improper slope hits the Therma-Tru sill directly. In Pomona’s combination of hot, dry summers and occasional heavy winter rains, that moisture cycle swells and shrinks the composite sill until the seal fails.
- Pavers rocking or sounding hollow when stepped on. The base course - usually Class II road base in our local builds - has washed out or settled unevenly. This transfers load stress to the door threshold and can crack the riser assembly.
- Weeds or grass growing through paver joints. Polymeric sand has degraded or was never properly installed. The gap allows water to penetrate to the bedding layer, undermining the edge restraint that keeps pavers aligned with the door threshold.
- Door sticks or drags at the bottom. Pavers have heaved upward, closing the threshold gap. In the Ganesha Hills area of Pomona, we’ve tracked this to expansive clay soils that lift pavers 1/4 inch or more in wet months.
- Visible gap between threshold riser and paver surface. The riser has pulled away from the subfloor, usually because the fastening schedule was insufficient for the load path from foot traffic hitting the threshold edge.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Pomona |
|---|---|
| Threshold/sill pan replacement with paver adjustment | $800-$2,200 |
| Paver driveway section removal, base repair, reinstall (up to 100 sq ft) | $2,500-$5,500 |
| Full paver driveway replacement | $7,000-$18,000 |
| Concrete driveway replacement with proper slope to door | $4,500-$12,000 |
| Edge restraint and drainage correction only | $1,200-$3,000 |
The range depends on three factors: how far water has traveled into the substrate, whether the Therma-Tru sill pan can be salvaged, and whether we need to regrade the approach to meet Pomona’s municipal drainage requirements. Under Clause 1 of the Haven Standard, you get a written price before anyone picks up a tool - every line item listed, no call-for-a-quote runaround. The 365-Day Done Right Promise covers the installation; manufacturer defects on Therma-Tru components fall under their warranty, which we document and file on your behalf.
DIY or Call Us?

There’s honest work a homeowner can do: pull a few pavers to check for standing water in the base, verify the slope with a 4-foot level, or clear weep holes in the Therma-Tru sill pan with a piece of wire. What goes wrong fast is lifting the threshold assembly itself - the sill pan is part of a system that includes flashing ties to the rough opening, and disturbing it without understanding the load path risks water intrusion behind the wall.
We’ve also seen DIY paver resets that look level until the first rain, when the uncompacted bedding layer settles and the door drags again. Measure twice, then we can talk. If you’re seeing threshold damage, call (626) 606-1081 and we’ll schedule a free estimate with a written scope and photo documentation of what we find.
FAQs
With proper base prep and drainage, 20-30 years for the paver surface, though the polymeric sand joints need refreshment every 5-7 years and the threshold assembly may need attention at 10-15 years due to our thermal expansion cycles. Call (626) 606-1081 for an exact quote - estimates are free.
Sometimes. If the composite sill is surface-stained but structurally sound and the sill pan flashing is intact, we can adjust the paver slope and reset the riser. If the sill pan is cracked or the subfloor shows moisture damage, replacement is the only fix that lasts. Call (626) 606-1081 for an exact quote - estimates are free.
Threshold work with localized paver adjustment: one day. Full section removal and base repair: two to three days, plus a 24-hour cure period for any concrete footing work before paver reinstall. We don’t proceed to the next phase until the previous one is documented and signed off. Call (626) 606-1081 for an exact quote - estimates are free.
We carry common threshold caps, composite risers, and sill pan extensions for Classic-Craft and Fiber-Classic series; full door slabs and specialty sizes are ordered through distribution with a 5-10 day lead time. For paver base materials and edge restraints, our Pomona warehouse stocks Class II base, polymeric sand, and PVC edge systems - enough to handle most same-day starts on repair work. Call (626) 606-1081 for an exact quote - estimates are free.
We also stock parts and materials for KraftMaid, Cambria, and Silestone products.
