"Excellent job.  My wife was very concerned because we had a graduation party in just 2 weeks. 
Pawel was able to start within 3 days of his estimate and they finished the
work just 4 days after they began.  They even worked over the weekend. 
They were very clean, polite, and I felt very safe with them working with just
the nanny and our kids at home.  I've already contracted him for future
work at my apartment building and I plan to continue to use his team in the
future.

"I've been working with John and his sub contractors on this property since August of 2013, and they have been patient, responsive, and transparent throughout, especially appreciated when my property insurance had to get involved and they worked with them to get them details, quotes, and insight, as well as being a much-needed professional advocate that I never would have been able to accomplish on my own. I have no doubt that John's professionalism helped speed the process along.
When I realized I would have to switch contractors from my first GC, out of everyone I called, John was the only one who brought someone with him for a second opinion on his assumptions, and even sent additional subs out to ensure the accuracy of the quote. I have had nothing but great experiences with him and everyone he works with since.

"This is my second project with Fil and Thor Build. The idea to construct a mezzanine was something that I had envisioned when I first saw my condo. I showed Fil my ideas on paper along with photos of how I wanted everything to look. Fil ran with it and brought it to fruition. Everything turned out even better than how I had envisioned. During the project, I requested some modifications which Fil gladly accommodated; he even created a custom door for me that is absolutely stunning - the quality work of artisans! To top it all off, this project was completed while I was 600 miles away. I had to rely strictly on photos and good communication. I had tons of questions during the construction phase and I'm sure I must've drove Fil crazy at times. However he was always professional and answered all of my questions and addressed any concerns that I had. I can't say enough about Thor Build, they are my go-to contractor and I am so fortunate to have found them."

"Beyond four walls was originally hired to re-do my floors, which turned into gutting our house, reimagining the floor plan, remodeling two bathrooms, the kitchen and additional upgrades. The upgrades consisted of paint, insulation, a tankless hot water heater, pex water pipping, electrical outlets, lighting and the fuse box. We did so much I’m sure I’m missing things. Courtney and his family did all the work and we would hire them to do it again!"

"John and his team were fantastic. We were considering purchasing a home and found out it had a laundry list of city violations that would need to be corrected before we could move in. He and his team met with us on three separate occasions to walk through the property, look at the work that needed to be completed, and gave us several estimates for all the work. They were prompt, professional, and thorough, and took the time to answer all of our questions and create detailed estimates with different options for us. Unfortunately, it was just going to be too much money to fix the house and we ended up backing out of the purchase contract, but we will definitely call Fogarty Home Improvement first for any future need.

Home Building FAQs, answered by experts

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.
