Walking into that split-level on Carlton Road last Tuesday, I smelled it before I even reached the basement stairs – that sweet, musty odor that tells me there's moisture where it shouldn't be. The homeowner kept talking about the "recent renovations" while I stared at water stains creeping up the foundation wall behind their brand-new drywall. Three hours later, I found the source: a cracked foundation that's been weeping for months, maybe years. The buyers were ready to close in two weeks on this $785,000 house.

That's Unionville for you – beautiful homes with expensive problems hiding underneath. I've been inspecting houses here for fifteen years, and I'll tell you what I find most concerning: buyers see the manicured lawns and prestigious schools and forget these homes average thirty years old. Age means systems are failing. It means shortcuts from decades past are coming back to haunt you.

Just yesterday on Bur Oak Avenue, I crawled through an attic where someone had blown in new insulation right over knob-and-tube wiring. Looks great from below. Fire hazard from above. The electrical panel hadn't been updated since 1987, and half the circuits were overloaded. You want to know what that rewiring job costs in Unionville? I'm seeing quotes around $12,800 for a typical four-bedroom. Add another $3,200 for the panel upgrade.

Sound familiar? Here's what buyers always underestimate – the cost of bringing these older homes up to code. I inspected a gorgeous colonial on McCowan Road two weeks ago, listed at $820,000. Hardwood floors throughout, granite counters, the works. But the HVAC system was original to the house, struggling to heat 3,200 square feet. The furnace was short-cycling, the ductwork was undersized, and the previous owner had sealed up half the return air vents during their kitchen renovation.

Guess what we found when I pulled off that beautiful crown molding? Mold. Black streaks running along the baseboards where condensation had been building up for who knows how long. The buyers were looking at $18,500 for a complete HVAC overhaul, plus remediation costs I couldn't even estimate without bringing in a specialist.

That's the thing about Unionville's housing market – properties move fast because everyone wants to live here, but that speed kills due diligence. I'm seeing homes sell in under twenty days, and buyers feel pressured to waive inspections or rush through them. In fifteen years, I've never seen that approach go well. Not once.

Take the house on Village Parkway I inspected last month. Stunning curb appeal, private lot backing onto green space, asking $847,000. The sellers had staged it perfectly, fresh paint throughout, new light fixtures. But I always check what's behind the pretty facade. The roof was a patchwork of repairs, with three different types of shingles telling the story of years of leak problems. The attic insulation was compressed and wet in two corners. I found daylight streaming through gaps in the soffit.

The roofing contractor I recommended quoted $16,200 for a complete tear-off and replacement. The buyers negotiated that into the purchase price, but how many people would have spotted those issues during a weekend open house? You're not looking up at soffits when you're admiring granite countertops.

What I find most troubling are the basement issues I keep seeing in this area. The clay soil here doesn't drain well, and builders in the nineties didn't always account for that properly. I've inspected four homes on Copper Creek Drive in the past year, and three had foundation problems. Hairline cracks that homeowners painted over. Window wells that weren't properly waterproofed. Sump pumps that hadn't been tested in years.

Foundation repair isn't cheap anywhere, but in Unionville's market it's devastating. I watched one family walk away from a $798,000 purchase after my report showed settling issues that would cost $22,000 to fix properly. The sellers ended up taking the house off the market to address the problems themselves. Smart move, but imagine if those buyers had discovered this two years after closing.

Here's my honest opinion after inspecting over two thousand homes in this area: the properties built between 1985 and 2005 need the most attention right now. They're hitting that age where major systems start failing simultaneously. I'm talking furnaces, water heaters, roofing, windows – everything installed during construction is reaching end-of-life at the same time.

I inspected a beautiful executive home on Rodick Road just before Christmas. The sellers were asking $891,000, and it looked perfect. But the forty-gallon water heater was twelve years old and showing signs of corrosion around the base. The central air unit was making noise the homeowner had gotten used to but shouldn't ignore. Both garage door openers were failing. The list of "small" repairs added up to $8,400.

None of these were deal-breakers individually, but together they paint a picture of deferred maintenance. Buyers always ask me if they should be concerned about these older systems. My answer? Plan for replacement, don't hope for the best.

Looking ahead to April 2026, I expect we'll see more of the same. These Unionville homes aren't getting younger, and the maintenance needs aren't disappearing. The difference between a good purchase and an expensive mistake often comes down to knowing what you're buying before you sign.

If you're serious about buying in Unionville, don't let anyone rush you past the inspection stage. I've seen too many families learn expensive lessons they could have avoided with three hours and a thorough review. Call me before you fall in love with a house – I'd rather protect you from a costly mistake than watch you discover problems after it's too late.
