Experienced professional - Over 35 years of professional contract work completed. I specialize in structural repairs including Field Stone Foundation - Sill Replacements, Lally Columns, Footings, Beam Replacements - Antiques Bought - that are being listed to be sold. I am fully licensed and insured. Services do not include crack or foundation repair.

"Rene is the best! We reached out to Rene about structural issues on our old home. He responded promptly and scheduled a visit within a few days. He knew just what to do to address some sagging floors and areas of the house that weren't correctly supported. He did all the work himself (he sometimes has his son work with him). I have no idea how he was able to complete all the work on his own, especially pouring new concrete footings in a very small crawl space! He is a machine!!! He is meticulous in his work and really goes above and beyond. He left our basement cleaner than when he started!!! He’s a super nice man and it was a pleasure having him work on our house."

Home Building questions, answered by experts

Depending on size, customization, and location, costs range from $100,000 to $300,000.

Prefab kits like a small sunroom for around $20,000 or even a basic gazebo roof for as little as $60 can save you big over professional installation. However, you lose the option for customization, and these structures tend not to last nearly as long. As for bigger projects like a deck or patio, you shouldn’t go with the DIY route unless you’re fully prepped with the tools and know-how to get it done right. Mistakes can be frustrating and costly, so choose a pro if you’re looking to eliminate your risk of error.

The average guest house is between 600 and 1,500 square feet. If you are unsure of how large you should build it, a good basic rule is to have one bedroom for every two occupants, at minimum. Generally, one bedroom for every one to two people is a good ratio. 

Due to the expansion of the tiny house movement, you can usually find tiny houses to buy in your state. Prices range considerably based on size, style, and type. If you’re looking for a tiny home that’s move-in ready, you may be able to find a good deal to buy or a prefab dealer near you. 

Framing tends to be the longest step in the construction process, especially for larger homes. It takes anywhere from one week to a couple of months, depending on the house size, the number of people on the construction crew, and the time of year. The design stage often takes a long time, too. Some people spend months or even years contemplating their house’s size, layout, and materials before construction begins.
