Adding on to your house can be either a very rewarding experience. Or it can be a nightmare. If you follow certain procedures, however, the whole process can be relatively trouble-free.

Most importantly, find a reputable contactor. The best way is referral from someone you trust who has actually had work done or is in the building trade.     Check out the contractor with the Better Business Bureau.

Get several estimates. This will allow you to have a better idea of what is involved and available to you.

Don't let price be the main reasoning to base a decision upon.

Have a written contract drawn up and reviewed by a lawyer. There is a standard builders contract many companies use but there are areas in it that could be tightened up. If your contractor balks at making any changes give the deal a second thought.
If the contractor wants the bulk of the money up front, don't agree to this. Once your money is tied up, you are at their mercy with little recourse if they drag out the process. The ideal situation would be to have a certain percentage of the work done and then pay for that work.

Be concerned if the work is being subcontracted. Make sure that there is something in the contract to insure that the subcontractor is paid. If the main contractor doesn't pay the subcontractor you are still responsible and the sub can put a lien against your house for payment.

Have plans drawn. It helps clarify your dream plan with a builder if you provide photos of what you want.

Make sure there is a reasonable time limit written into the contract. It is important to have a reasonable target date for completion.

Get a warranty on the work and materials or fixtures purchased.

Once work starts, be sure to be around. Don't be afraid to ask questions. Remember, they are working for you and you have every right to be informed and know what is going on.

By monitoring the work, you have a good idea of how things are coming along. Communications is the key word here. Talk with your contractor on a weekly, or if possible, daily basis.

Make certain openings on the roof or walls are covered at the end of each day. This will deter intruders but most importantly will keep the house dry in case of rain.
Treat the workers as you would like to be treated. If the weather is hot outside offer them something cold to drink.

Be sure when the job is finished, everything meets contract specifications. Don't sign off on the work until you are satisfied.

Remodeling can be a trying situation, even under the best of circumstances. If you follow the above suggestions, it can go a lot smoother. Most contractors are reliable, honest, and want to do a good job. But if you have a problem, don't hesitate to let them know about your concerns. And if problems do arise, be sure to talk with your lawyer about what actions you may need to take if the contractor doesn't address your concerns.

Always try to be positive. There will be glitches that arise but most can easily be solved by simply talking to your contractor. When all is said and done your new addition will be done fairly quickly for you to sit back and enjoy.
