"I had an addition I wanted for our home. We were required to have a survey and an engineer drawing to apply for the permit. I had a list of 10-15 local engineering companies given to me by the permitting office. Very few would return my call. several the rest said they only do commercial or that this was too small of a job and would cost more. It was taking months and I was frustrated and decided to try Angie’s. I am so pleased. I had a response that very day I inquired for the job. It was clear what was needed from me. Great communication and answered questions to help me get them what they needed. The project from start to finish was drafted within 3 weeks.

FAQs for treehouse building projects in Cornwall, CT
The average cost to hire a handyman ranges from about $40 to $140 per hour. Average project cost ranges between $180 and $700, but the cost per hour and per project depends heavily on the type, size, and complexity of the project. The pro’s experience level and your location also factor into how much a handyman charges per hour or per project. You can also expect to pay higher rates or additional fees for emergency services, or around periods of high customer demand, like holidays.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
The cost to build a detached garage for two cars costs about $26,400 on average.

Additional cost factors include any plumbing, electrical wiring, and insulation. If you need to build a concrete foundation for a new detached garage, you can expect to pay $1,000 to $8,600 for this essential addition.
