sunrooms
If you are considering adding a sunroom design to an already existing house, just make sure you find yourself a good reputable company that specializes patio designs and sunrooms. Many companies provide this service as an add on to their already existing business, and do not specialize in this service. If you find a company like that they may wind up giving you less than what you are expecting. I have heard some real horror stories about sunrooms that leak and problems with the structures not being sturdy enough, and even some stories about sunrooms half finished and left that way by less than reputable companies.
The question then really is how do I know if I am using a reputable company to build my sunroom? And the answer is very simple. You need to do the research to find out exactly what you need to know about the company you are considering using, prior to paying them any money. There are simple things that you can look for or ask about when you are checking into a company. You can always check them out with the Better Business Bureau and if they have a good rating with them that is a really good sign. A rating of AAA is the best rating and the Better Business Bureau can also tell you if the company has had any complaints filed against them and if so for what. There are other things that you can look for like the Good Housekeeping Seal, Energy Star Certification, and AAMA Gold Standard Certification (this is an architectural certification and insures that you will get the best quality structure).
Looking thoroughly into any company before you use them to do work on your house is always wise. Keep in mind that for most people their primary investment is their house, and making sure that whatever work you have done to it is of the utmost quality is extremely important. It can be a little time consuming to look into the background of a company that you are considering to do work for you, but it is well worth the investment to insure that you are happy with the finished product.
