Whole house renovation companies take on the jobs that touch every part of a home: design, demolition, framing, plumbing, electrical, heating, insulation, drywall, tile, cabinets, floors and paint, run in the right order by one team. Choosing one is mostly about seven checks, covered one by one below, starting with finished whole-house work in homes like yours, proper registration and insurance, and a detailed estimate with clear allowances. This guide explains each check, the red flags and the questions to ask on the first call.
Norman Builders is a design-build home builder and remodeler founded in 2007 by Ryan Norman, with an office in Newton, NH. We renovate whole houses and first floors across the Merrimack Valley, the North Shore, the Seacoast and southern New Hampshire. We are one of the companies you might compare, so where this guide uses our projects and client reviews as examples, they are labeled as ours.
What a Whole House Renovation Company Does
A kitchen or bath remodel involves a handful of trades. A whole house renovation can involve a dozen or more, and the order matters: structure before systems, systems before insulation, inspections before walls close, and finishes last. The company you hire is responsible for that sequence, the permits and inspections, ordering materials with long lead times, and dealing with what turns up when old walls are opened.
That coordination is most of what you are paying for. Bill M., an Andover client, described two projects that "required a number of subcontractors all managed through Norman Builders."
Types of Companies You Will Meet
- General contractor working from your architect's plans: you hire an architect or designer first, then put the finished plans out to bid. Good when you want an independent designer; the risk is a design that comes in over budget after you have paid for it.
- Design-build company: one company handles design and construction under one contract, pricing the design as it develops. Our guide to comparing design-build companies covers firm types, design fees and the questions specific to design-build.
- Single-trade or handyman businesses: fine for one room or one trade, but a whole house needs someone licensed to supervise structural work and able to run every trade.
How to Choose a Whole House Renovation Company: 7 Checks
1. Finished Whole-House Work in Homes Like Yours
Ask to see two or three whole-house or full-floor projects, not just kitchens and baths, and ask how old those houses were. A company that renovates 100-year-old New England houses has dealt with plaster, out-of-level floors and old wiring; one that mostly updates newer homes may price those surprises poorly. When the North Andover owners of our luxury whole-home renovation were choosing a builder, they wanted one team to handle design and construction and hired us after reviewing our portfolio and talking through their goals.
2. Registration, Licenses and Insurance
In Massachusetts, contractors doing most work on existing owner-occupied homes must be registered Home Improvement Contractors, and whoever supervises structural work generally needs a Construction Supervisor License. New Hampshire does not license general contractors at the state level, but electricians and plumbers are licensed in both states. In either state, ask for certificates of liability insurance and workers' compensation, and for a house built before 1978, confirm the firm is lead-safe certified. Our contractor license guide explains each credential and how to look one up.
3. An Itemized Estimate With Clear Allowances
A one-page number is not an estimate for a whole house. You should see the work broken out by phase or trade (demolition, framing, plumbing, electrical, HVAC, insulation, finishes) and every allowance, the placeholder amounts for items you have not picked yet, such as tile, fixtures and cabinets. Allowances that are too low are the most common way a fair-looking bid turns into a larger bill. John H., whose Newmarket, NH remodel included gutting bathrooms, an addition and a new roof, wrote that "Ryan's bid for our remodel was concise, detailed, and reasonable." Linda B. of North Andover described how an allowance budget worked on her bathrooms: "He also provided an allowance budget to give us an idea of what the total project would cost." Her upgrade choices took the total over that original budget, but she noted that "Ryan did not exceed his labor estimate." Our renovation cost estimator guide lists what an estimate should include.
4. Who Runs the Job and Who Does the Work
Ask who will be your day-to-day contact, who is on site, and which trades are the company's own people or long-time subcontractors. Crews that have worked together for years usually sequence a job better. Virginia T., whose major Andover renovation ran from June to November 2014, noted that "Ryan's sub contractors were excellent and did quality work. Most have worked for him for many years."
5. How They Communicate
Ask how often you will get updates, how fast calls and texts are answered, and how decisions you need to make are flagged ahead of time. Dan M., whose Andover project included structural work, roofing, plumbing, HVAC and sewer work, wrote: "Ryan's communication throughout the project kept us informed of what was happening, what was going to happen next, and decisions we needed to make to keep the project on track."
6. How Changes Are Priced
Every whole house renovation has changes, from homeowner add-ons to problems found behind walls. Ask how change orders are written, approved and priced before the work is done. Virginia T. wrote: "As with all jobs, there were a number of changes and add-ons and we believe Ryan always gave us a reasonable price." Our whole-house renovation budget guide covers contingency and change orders from the homeowner's side.
7. Schedule, Living Arrangements and Closeout
Ask for a realistic schedule, whether you will need to move out, and how the end of the job is handled. Our renovation process guide puts a whole-home renovation at about 4 to 12 months or more. In our design-build process, walk-throughs near completion produce a punch list of final items that the team then completes. Get any warranty terms in writing before you sign, and ask how the company handles a call six months after the job is finished.
Red Flags
- A large deposit up front. In Massachusetts, the Home Improvement Contractor law generally limits a deposit to one third of the contract price, or the cost of special-order materials.
- No written contract, or a contract with no scope, schedule or payment terms.
- A bid far below the others with low allowances or vague line items.
- A request that you pull the permit yourself. In Massachusetts that may reduce some of the protections of the Home Improvement Contractor law, so ask your town and the contractor how it works.
- No whole-house references, or references only from small jobs.
- No answer to "who will be on site every day?"
Questions to Ask on the First Call
- Which whole-house or full-floor projects have you finished in the last few years, and in homes how old?
- Are you registered and licensed for this work in my state, and can you send your insurance certificates?
- Do you handle design, or do I need my own architect or designer?
- Will the estimate be itemized, and which items will be allowances?
- Who runs the job day to day, and which trades are your regular subcontractors?
- How do you write and price change orders?
- Who pulls the permits, and how do inspections fit the schedule?
- Will we need to move out, and for how long?
- What happens at the end: walk-through, punch list and warranty?

Frequently Asked Questions
Should I hire an architect first or a design-build company?
Either can work. An architect first gives you an independent design, but you will not know the construction cost until the plans are bid. A design-build company prices the design as it develops, which helps keep a whole house renovation inside the budget. If your town or project needs stamped drawings, a design-build company works with an architect or engineer for those.
What licenses should a renovation company have in Massachusetts and New Hampshire?
In Massachusetts, Home Improvement Contractor registration for work on existing owner-occupied homes, a Construction Supervisor License for whoever supervises structural work, and licensed electricians and plumbers. New Hampshire has no state general contractor license, but its electricians and plumbers are licensed. For homes built before 1978, the firm should also be lead-safe certified.
How many companies should I get quotes from?
Enough to compare like with like. Two or three detailed, itemized bids for the same scope tell you more than many one-page numbers. Compare the allowances and what each bid leaves out, not only the totals.
