What New Hampshire Homeowners Say
Reviews from real customers who have completed projects with New Generation General Construction. Every review appears exactly as submitted through Google.
The kitchen remodel came in on schedule and on budget. Miguel was clear about materials and pricing from the first estimate. Would hire again for future work.
Roof was replaced after a bad ice storm and the crew handled the tear off, flashing and new shingles in three days. Site was cleaned every night before they left.
Called about a leaking gutter and had someone out the next morning. Written estimate the same day, work done the following week. Direct communication throughout.
Bathroom demo, plumbing and tile were all handled by the same crew. No surprise charges on the final invoice and the finish work was clean.
Siding replacement on an older home. The old material was removed properly, rot was addressed and the new siding looks square and clean. Owner on site checking work.
New deck installed on footings that hold. Railings and stairs matched to the existing house exterior. Timeline held to the written schedule.
Frequently Asked Questions
Straight answers to the questions we hear most from New Hampshire homeowners before starting a project.
Are you licensed and insured?
Yes. New Generation General Construction is licensed and insured in New Hampshire. Miguel has fifteen years in the trade. You will see proof of both before any work starts on your property.
How much does a remodel cost?
It depends on the size of the space and the materials you pick. That is why the estimate is free and itemized. You will see materials, labor and timeline before you commit.
Do you charge for estimates?
No. Estimates are free and there is no obligation to book. We come out, measure the work, and send the numbers in writing. If the price does not work, that is fine.
How long will my project take?
Every job is different, so we do not guess. Once we have seen the space, you get a real schedule in the written scope. Weather can shift exterior work, and we will tell you.
Do you handle emergencies after hours?
Yes. We are available 24/7. If a roof is leaking, a gutter has torn loose, or water is getting into the house, call us. Do not wait until the morning.
What areas do you cover?
We work in New Hampshire and the surrounding area. If you are not sure whether your address is in range, call or send the form with your ZIP code and we will confirm.
Can you do interior and exterior work?
Yes, and that is the point of hiring a general contractor. Kitchens, bathrooms, carpentry, roofing, siding, decks and gutters run through one crew. You are not chasing five different companies.
What are your hours?
We are on job sites Monday through Saturday from 7 AM to 5 PM, and Sunday from 8 AM to 3 PM. Emergency calls get answered outside those hours too.
