"I contacted Cully because of his ratings on Angie's List as it is very hard to find a reliable contractor in this small town where we own apartments.
Cully immediately got back to me - we discussed what work needed to be done and he had a very professional proposal emailed to me within 24 hours.  The price was right on target for work performed and we are very satisfied with his work.   Initially, we agreed for him to sheet-rock 2 ceilings but found that he was so knowledgable and handy so we also had him put up paneling.
We did not have him paint the interior as we did that ourselves (he did paint the ceilings when completed).  Come spring time, I will hire him again to do some exterior painting.  He is my first "go-to" now when we need repairs, painting, or sheet-rocking done.  He cleaned up each time he finished working, making it look better than it had before he started.  
Cully was always on time and in communication with me either by phone or email so I knew where the project stood at all times.  He even suggested an electrician and was there to let him in and explain what we wanted done when we had to upgrade our smoke detectors.
I would highly recommend Cully, he went above and beyond what was asked of him.

"Chris did a good job giving us what we asked for. Only issue was a few screws missing in the deck and one of the gates rubbing after only a couple months. I corrected the issue and all is good."

"Jeff and his crew were respectful of our property. Estimate came very close to final bill. Always kept us informed of delays or additional materials needed. The roof and a front porch addition over concrete steps came out beautiful. Jeff knows what he is doing and advises a homeowner appropriately. Will recommend to others and will call again for the next project."

Home Building FAQs, answered by experts

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?

Yes, a home builder or contractor should have the proper licensing and insurance. Licensing requirements vary by state and municipality, but most states mandate that a builder holds at least a general contractor’s license. For specialized work such as plumbing, electrical, roofing, or sewage systems, individual licenses may be required, in which case the builder may subcontract the work. You can use Angi’s state licensing tool to review your local guidelines and confirm a builder's credentials. As you browse professionals, you can also look for the “Angi Certified” badge. This indicates the business meets our certification standards, which include passing a criminal background check, holding applicable state and local licenses, and maintaining an average rating of 3.0 or better.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.
