"Andy and his crew were extremely personable and communicative with me each step of the way. I got exactly what I hoped for, sooner than expected, and under budget! They took the time with me to even go to Lowe's and pick out flooring pieces that I took back to the house and matched to my hardwood floors so that everything has continuity. I couldn't be more pleased. I highly recommend D Squared Contracting."

"It is a waste of money. The great majority of people are not going to find any value out of the service. If you need design consultation, you need a full service consultation. If you already have knowledge and experience, and you just need to get a few ideas, then you don't need to pay for that. You can just get a magazine or a book since you already have the knowledge of basic designs in your head or a little bit of experience. To have someone call you and give you information over the phone, you are not getting the personal service that you need. You may as well take the money $49 and apply it to something else like getting someone else to come out and give you the service that you need. Because, you are not getting much, you are not getting anything at all. They are going to have you do the work. After talking to them and I was talking to other home designers, I found out that that was a waste of time and waste of money. I gave them a C because they didn't fail at what they do but they don't offer any value for what they do. There's not much value to it. The cost was fair. They didn't do a terrible job and the cost isn't terrible, it was only $49. It just has a very low value. For responsiveness I gave them a B because they will answer your phone and answer your emails."

Unfinished Carpentry FAQs, answered by experts

Using a steel frame may raise the value of your home. Steel is more heat resistant, has better longevity, and doesn’t need any upkeep compared to traditional wood. You can also customize a steel build a little easier than other materials like brick, concrete, and vinyl—which have trouble bending and adapting to renovations.

Most of the time, you’ll want to use screws on your subfloor rather than nails. Nails can actually weaken plywood, whereas screws can easily penetrate without damage. They also form a more secure connection because of their shape, preventing squeaky floors and tightly holding the subfloor in place. That said, some contractors do prefer nails depending on the type of floor covering because they allow for more flexibility.

Converting a carport into a garage can vary in difficulty depending on its configuration, the condition of the foundation or slab, and its location relative to the house. The process has a lot in common with a home addition, but you can often skip non-essential finishes like fine flooring, trim work, or even drywall and HVAC. The conversion requires experience with drywall, insulation, and other building materials to ensure it’s done safely and correctly. While it might be possible for a DIYer with the proper tools and skills to do the work, it is a complicated and potentially dangerous job. If you’re new to basic construction, it's best to leave this project to the professionals.

Framing is the shell of the house. It includes several steps, including studs, plumbing, and electricity. A professional will ensure the wall frame is secured for the house’s structural integrity. 

Framing prices change depending on the material and whether the wall is load-bearing. Most contractors use wood to frame a home, but metal is another popular choice.

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors.
