The same small crew handles your project from the first measurement to the last coat – no rotating subcontractors, ever. We price everything line by line so nothing is hidden, run vacuum-assisted equipment that captures 95% or more of sanding dust, and finish with Bona and Loba products that are kid- and pet-safe once cured.

Darien's mix of mid-century ranches, split-levels, and newer subdivisions means the right approach changes from house to house. Here is how we adapt by home type and condition:
1
1960s-1970s ranch and split-level homes: Most of these Darien homes were built with plywood or plank subfloors over a basement, which is ideal for nail-down solid hardwood. Original strip oak in living and bedroom areas is often still sound and worth refinishing rather than replacing. For any home built before 1978, we follow EPA lead-safe RRP containment protocols.
2
Mixed slab and framed sections: Ranch and split-level additions or family rooms frequently sit on slab-on-grade while the main living areas sit over a basement. We check each section and switch methods accordingly – glue-down or floating engineered systems on concrete, nail-down on framed floors.
3
1990s subdivisions and custom homes: Neighborhoods like Darien Club tend to feature larger open-plan spaces and wider-plank hardwood over plywood subfloors. We verify subfloor flatness and moisture levels before installation so seasonal movement does not open gaps or create squeaks.
4
Prior installations and updated interiors: Many Darien homes have already been through at least one renovation. We commonly encounter floating laminates, tiled entries, or earlier hardwood installs that need demo and subfloor leveling before new work can begin.
5
Freeze-thaw humidity swings: Cold dry winters and humid summers put real stress on hardwood. We acclimate every job on site and recommend keeping indoor humidity between 30-50% year-round to prevent cupping, gapping, and crowning.
In many Darien homes the original wood is worth saving rather than replacing - but the only way to know is to look at the subfloor and boards up close.

This one speaks for itself. A homeowner in Darien had a 1970s ranch with original hardwood floors that had taken decades of foot traffic, pet scratches, and a finish so dull it barely reflected light anymore. We sanded them back to bare wood, repaired the damaged boards, and refinished everything - same floors, no replacement. Take a look at the before and after photos below and judge the results for yourself.

Almost certainly yes. Many 1960s and 1970s ranch homes in Darien were built with red oak strip flooring in the living and bedroom areas, and it holds up well over the decades. We inspect the boards first to confirm there is enough wear layer remaining, then sand with vacuum-assisted equipment that captures 95% or more of dust. We finish with low-VOC Bona or Loba coats that are safe for kids and pets once cured. Refinishing from $3 per sq ft.
We see this layout regularly in Darien split-levels and raised ranches. Framed sections over a basement are well-suited for nail-down solid hardwood. Slab areas, common in family room additions or lower levels, call for a glue-down or floating engineered system instead. We check moisture levels and subfloor flatness in both zones before we start, so the right method goes in the right place. We will walk you through the options at your free in-home estimate.
It does. Darien winters are cold and dry, and summers are hot and humid, so wood expands and contracts significantly across the seasons. We acclimate every board on site before installation and follow NWFA guidelines for expansion gaps. We also recommend keeping indoor humidity between 30-50% year-round to minimize movement and prevent gapping or cupping. Over basements or slab sections, we add appropriate vapor control to keep moisture from migrating up into the wood.
Yes. A meaningful number of Darien homes from that era fall into the pre-1978 lead-paint category. When they do, we follow EPA Lead RRP protocols, which means proper containment, HEPA-filtered equipment, and verification procedures throughout the job. Our crew is trained and equipped for this, so you are not left to figure it out on your own. If you are unsure whether your home qualifies, just mention the build year when you call and we will advise you from there.
It depends mostly on square footage, the condition of the floors, and whether you’re refinishing or installing new. Refinishing starts around $3 per square foot; new installation costs more because of materials. You get an itemized price at the free in-home estimate, and you can get a rough number first with our online cost calculator.
Most refinishing projects take 2–5 days, depending on size, stain, and number of finish coats. You can usually stay home – we seal off work areas and keep sanding dust to a minimum with vacuum-assisted equipment – but you’ll need to keep off the floors while the finish cures (water-based finishes are walkable sooner than oil-based). We give you a day-by-day plan before we start.
For most projects, we take a deposit to cover materials and lock in your dates, with the balance due once the work is finished and you’re happy with it. We put the exact terms in writing at the estimate, so there are no surprises.
Tell us what you need — we’ll help you figure out the best way to get it done.
