Home Inspections in North Castle, NY for Armonk, Banksville & North White Plains

Know the House Before You Buy or Sell in North Castle

A home inspection in North Castle, NY starts with one number: by the town’s own count, over 90% of residents draw their water from private drilled wells. Unless the home sits in one of the town’s five small water districts, like downtown Armonk’s, it almost certainly runs on a well and a septic system. Those are the two systems a fast checklist inspection skips, and the two that cost the most after closing.

Home Inspection Services in North Castle, NY

Longs GCS LLC ASHI-certified home inspectors

Buyer's Inspection

A full ASHI-standard inspection, roof to foundation, before you commit. On most North Castle properties that includes the well equipment, the septic, and how a wooded lot drains, because that is where the expensive surprises tend to be.

Pre-Offer Walkthrough

Thinking about an as-is offer? Chris walks the home with you before you sign and points out the red flags that should change your number: a roof near the end of its life, dated mechanicals, signs the septic is struggling.

Pre-Purchase Inspection

The full deep dive before closing. Doors, windows, plumbing, electrical, HVAC, attic to basement, tested and photographed in a report you can hand straight to your attorney.

New Construction Inspection

New builds need inspecting too. We come in after completion, before your final walkthrough, and catch what the punch list missed: dead outlets, unconnected vents, grading that sends water toward the foundation.

Pre-Listing Inspection

Find out what the buyer's inspector will find before they do. With North Castle requiring periodic septic inspections in the watershed areas, walking into a sale knowing your tank's condition is worth real money at the table.

Yearly Maintenance Inspection

A once-a-year check that catches small problems while they are still small. Especially worth it for homes with wells, septic, and the multi-zone systems larger houses carry.

When you choose Longs GCS LLC for your North Castle home inspection, one visit covers it: general inspection, radon testing, mold assessment, water-quality testing, and HVAC evaluation.

Nearby, we cover Chappaqua, Pleasantville, and Bedford Corners as well, and the full list is on our service areas page.

What We Commonly Find in North Castle Homes

Most of the town runs on wells and septic, and its two housing markets bring their own issues we look hard at.

Private Wells & Water Quality

Flow, pressure, pump condition, and water testing for bacteria and nitrates. The town has reported PFOA detections in some district wells, so we test district homes too.

Septic Systems

Failing tanks, saturated leach fields, and bad grading. North Castle requires septic inspections every five years in the Kensico and Croton watersheds.

Radon

Zone maps put Westchester lower on average, but the EPA recommends testing every home. We test so you know your number.

Buried / Underground Oil Tanks

In older oil-heated homes we look for fill pipes, vent lines, and other signs of a buried tank, a real environmental and resale liability.

Drainage & Grading on Wooded Lots

Wet basements and foundation issues that start outside the house, common on North Castle's sloped, wooded lots.

North Castle Home Inspection FAQs

Straight answers to the questions we get most in North Castle.

Schedule Your Inspection
?Do you test well water and inspect septic systems in North Castle?
Yes. By the town’s count, over 90% of North Castle runs on private wells, so water testing and septic evaluation are core to what we do, not an afterthought.
?Is a septic inspection required in North Castle?
For properties in the Kensico and Croton watersheds, the town requires septic tank inspections at least once every five years. If you’re buying, an inspection now tells you whether you’re inheriting a compliant system or a looming repair.
?Should I test for radon in North Castle?
We recommend it. Zone maps put Westchester lower on average, but averages say nothing about your basement. The EPA recommends every home be tested, and we set the test during the inspection so results don’t hold up your closing.
?What determines the cost of a home inspection in North Castle?
The size and age of the home, and which services it needs: well flow and water testing, septic evaluation, radon, mold. A district-served house near downtown Armonk and a colonial on a Banksville well are very different jobs, which is why we quote each house rather than post a flat rate. Call (914) 260-8571 for an exact number.
?We’re relocating on a tight timeline. How fast can this happen?
Chris walks the property with you at the inspection, so you’ll know the big findings the same day. The full photo-rich report typically arrives within 24 hours.
