Questions homeowners ask
Are you licensed and insured?
Yes. Cairn Home Co. LLC is a registered New Hampshire company (NH business ID 1041950), fully insured on every job, with electrical and plumbing done by NH state-licensed professionals.
How soon can you come out?
Our line is answered 24/7, and we get someone out for a free estimate within 24 hours — weekends included. Urgent problems are handled right away.
Do you charge for estimates?
No. Estimates are free with no obligation. We look at the work, walk you through your options, and give a clear price before anything starts.
What areas do you serve?
Windham, NH and the surrounding Rockingham & Hillsborough corridor. Windham is home base, and we cover the surrounding towns.
Do you take on full remodels and bigger projects?
Yes. Kitchens, bathrooms, basements, additions and in-law suites, garages, roofing, siding and windows, decks and sunrooms, flooring, and built-ins. We act as your general contractor: one point of contact from design to the final walkthrough, licensed electricians and plumbers for the trade work, and permits and inspections handled for you.
How do you price a remodel?
After a free on-site visit we send a line-item, fixed-price proposal you can open online, with options to choose between where they make sense. Nothing starts until you approve it, and the price you approve is the price unless you change the scope.
What warranty do you give on a remodel?
Every remodel carries a 5-year written workmanship warranty from completion: if something we built fails because of how we built it, we come back and fix it at no charge. Manufacturer warranties on the cabinets, fixtures, flooring, and windows we install pass straight to you. Smaller service jobs carry a 12-month warranty.
Do you offer financing for larger jobs?
Ask us when we quote. We can lay out financing options for larger projects, and you get the same transparent line-item quote either way.
Do you still do smaller jobs?
Yes. TV mounting, grab bars, repairs, plumbing, electrical, drains, smart home, and 24/7 emergencies. One company for the whole list.
Can I reach someone for an emergency?
Yes. Call or text (603) 505-1091 any time. Leaks, no heat, and electrical problems are connected to our team right away.
