Tremron Home Additions & ADU: The Houston Owner’s Guide
If you’re in Houston and need a home addition or ADU built around existing Tremron pavers, retaining walls, or hardscape features, the installed cost typically runs $45,000 – $130,000 depending on square footage, foundation work, and how much of your Tremron product we’re matching or extending. Elmstead Remodeling Houston is an independent contractor, not affiliated with Tremron, but we plan additions and ADUs around Tremron block, paver, and wall systems every season, and we give you a written price before any work starts. Most Houston owners call us because they have a failing Tremron edge restraint, a settling paver base under a planned addition footprint, or a drainage problem where the hardscape meets the new structure, and they need someone to look at the interplay before the foundation crew ever arrives.
Which Tremron Models This Applies To
Tremron’s Houston catalog spans concrete pavers, retaining wall blocks, and slab products, and the compatibility question depends less on a model name and more on the unit’s dimensions and load rating. A home addition planned over or beside existing Tremron pavers needs to work with the paver’s actual thickness, usually 60mm or 80mm for pedestrian areas and 80mm for drive-rated sections. Where the new foundation wall meets a Tremron retaining wall, the connection detail changes based on whether you have the Stonegate, Coventry, or Highland wall unit, because each has a different setback and core width. We carry the spec sheets for the common Tremron units and measure every course before we write the scope.
On the OEM-versus-aftermarket question specifically for Tremron work: when we’re extending a paver field, the cleanest visual match comes from a fresh Tremron batch in the same color family, but sun fading over even two Houston summers means a brand-new unit next to a five-year-old paver will show a shade difference. We’re upfront about that, and we sometimes pull salvaged units from the site itself to weave in where the transition sits. Aftermarket concrete units from other Houston suppliers can work for structural backfill, but the chamfer angle and surface texture won’t match Tremron’s mold shape, so we don’t spec them where they’ll be visible.

Signs Your Tremron Home Additions & ADU Is Failing
- Edge pavers are drifting or separating from the field. This is almost always an edge restraint that has pulled loose in Houston’s clay soil, which heaves with every wet-dry cycle. Once the restraint lets go, the outer course starts walking, and a new addition’s slab edge will eventually expose the gap.
- Water pools against your Tremron retaining wall after rain. A wall that was dry-stacked without proper drainage stone behind it will push outward slowly. We see this most in Meyerland and Bellaire where the water table sits high in spring.
- You hear a hollow thud when the pavers are tapped near the house line. That means the base has settled beneath the pavers, usually from a downspout discharging straight onto the field. It’s a warning sign before you put addition weight on the same grade.
- Polymeric sand keeps washing out of the paver joints. If the joint sand won’t stay put after two Houston downpours, the pitch across the paver field isn’t carrying water away from the future addition footprint. This compounds quickly once a structure blocks the old drainage path.
- A Tremron block wall is showing stair-step cracks at the edges. This points to uneven bearing under the wall’s base course. Foundation crews need to know about it before they dig, because vibration from compaction equipment can accelerate a wall that’s already leaning.

AfterReplacement Cost & What’s Included
For the Tremeron-adjacent work on a Houston home addition or ADU, the full project range is $45,000 – $130,000, and the Tremron-specific portion (pulling and resetting pavers, rebuilding wall sections, adding base stone, re-establishing drainage) lands inside that number depending on square footage and access. An ADU build runs $90,000 – $220,000 when it includes foundation, framing, utilities, and finish work. The variables that move your price are paver field size, whether we’re removing and reusing your existing Tremron units or extending with new ones, wall height and condition, and the amount of base material we have to cut out and replace with compacted, wetted, properly graded stone.
Every estimate includes the written price before work starts, the cost of protecting your existing Tremron surface with plywood run paths and drop cloths where the crew crosses, and time for the end-of-day walkthrough so you see what was done. There’s no allowance for a “surprise” line item once we’re on site. The workmanship on Tremron resets and wall repairs falls under our 365-Day Done Right Promise: if it isn’t done right, we make it right.
DIY or Call Us?
You can safely do the visual checks: walk your Tremron pavers after rain, note where the water sits, flag loose edge restraint for us, and take photos of any paver that has dropped more than half an inch. What we don’t recommend is pulling up pavers, rebuilding wall courses, or re-grading next to a planned addition without understanding the soil’s bearing capacity in your specific Houston neighborhood. The hidden risk is that a homeowner resets the top layer and it looks good for two months, then the base settles and the water finds the foundation. There’s a high-tension version of this too: moving a stacked block wall segment without bracing it can put real weight on the wrong course. Call (254) 272-5240 and we’ll walk the site with you before anyone digs.
FAQs
Tremron concrete pavers and block routinely hold 20 to 30 years in Houston if the base was installed over compacted, free-draining stone and the edge restraint stays intact; what shortens that life here is poor drainage beneath the field and tree roots working in from the sides. Call (254) 272-5240 for a site review if you’re building an addition beside older Tremron work.
Yes, in most cases we can lift and reset a settled section, add or replace the base, and reinstall your original Tremron units, which keeps the color and wear consistent across the field; replacement only makes sense when units are cracked or the field has shifted so far that the pattern no longer lines up.
The paver and wall work around a Houston addition typically adds three to seven working days depending on field size and access, and we sequence it so foundation crews aren’t waiting on the hardscape crew; the full addition or ADU timeline is set in the written scope before work begins.
We keep our supplier relationships local and pull Tremron units and drainage stone from Houston yards on a per-project basis, which means the freshest color lot and no material sitting in the sun before your install; we also stock parts and finishes from KraftMaid, Cambria, and Silestone when the addition includes kitchen or bath surfaces.
If you’ve got Tremron hardscape that needs to work around a new room or ADU, call (254) 272-5240 for a free estimate. We’ll send someone who measures, marks the field, and writes the price down before a single paver gets lifted.
