How to Get Home Addition Estimates

Obtaining Home Addition Estimates starts with a Solid Home Addition Plan

By Mark J. Donovan

A home addition is an excellent way to expand your home’s living space. The key secret on how to get home addition estimates that are both accurate and within your budget is to first develop your own set of home addition plans and requirements.

Develop a Set of Home Addition Plans

To obtain accurate home addition estimates start by specifying the size of your home addition, and the location of it relative to your existing home. As part of this process, you may need to contact your local town zoning board or building inspector to fully understand what size of a home addition you can build and where you can locate it relative to your existing home and property.

Use a few stakes and string to mark the corner boundary points of your home addition. This exercise can be a useful for judging the size of your home addition and for helping get home addition estimates. Contractors that meet with you at your home can quickly obtain a better feel of the size and location of the home addition by seeing it staked out.

With the size and location of your home addition identified, continue to add detail and dimensional information to your home addition plans. Make sure to include information on interior walls, door and window sizes and locations, and roof lines.

Another important home addition planning task is to develop a separate list of key features and materials you want to have in the home addition.

By developing a thorough set of home addition plans, along with a list of key features and materials, you will be able to get home addition price quotes that are more accurate for your home addition project.

How to Get Home Addition Estimates from Contractors

The first step in getting home addition estimates is to find a few local contractors to bid on your home addition project. You can check the yellow pages, call friends and neighbors who have recently had home remodeling work done on their home, or use a national home addition contractor referral company. Home addition contractor referral companies are excellent resources for finding qualified, and pre-screened, home addition contractors.

Contractors in their database have been thoroughly vetted out to determine if they are reputable. There is no cost to the homeowner for using one of these home addition contractor referral companies. You simply fill out an online form for your unique home addition needs and they will pass on your information to 3 or 4 local contractors in your area. The home addition contractors will then contact you to set up a time to meet with you and go over your specific home addition plans.

When interviewing potential home addition contractors make sure you check their references. Typically the longer the reference list that a contractor provides to you the more likelihood that he has a solid reputation.

A long reference list usually means that he is proud of his work and has a longer history in the business. However, don’t go by just the length of the list, call 3 to 4 of the references. Contact a couple references that were associated with projects done recently and then another couple that were completed 2-5 years ago. You may also want to check with your local Better Business Bureau and confirm that the contractor is licensed in your state.
