You need to assess:
The best place to start asking about fencing companies is your family, friends and especially your neighbors. Other good sources of references include other contractors, management companies, and HOA. Your Home Owners Association may have restrictions on what kind of fence can be built, as well as colors. It’s always best to find out this information before you begin construction. They may also require you to submit plans, colors and an estimate to their architectural committee for approval before you begin.
Were you happy with the quality provided by the fencing company? Everybody has their own ideas of quality, so you should take a look at their fence and judge for yourself. Pay attention to see if the fence posts are straight. Are there visible cracks between the boards that should overlap? Do the gates operate properly?
If painted or stained, does the color look consistent?
Did they remove the old fence, and leave the yard clean after doing the work? Did they pick up nails or screws from the yard? If you are left to clean up after them, this will cost you more time, money and frustration.
This is a very important consideration. The entire experience, from beginning to end, needs to be as stress free as possible. Plus if the fence builder enjoys their job, the quality and attention to details will be better. The customers attitude can and will affect the entire fencing job. Hopefully this will be the first question you ask. If the answer to this question is “no” then do not go any further, you don’t want to work with that person.
A good fence company uses quality materials and has a high level of expertise. Most reputable fence companies carry a one year workmanship warranty.
