Holztman home improvement is a dissaster waiting to happen. nothing but lies and excuses. | VERY unorganized co. that will take your money and not follow through with there promises. the contracts they use are 100% for the company. Zero protection for the consumer. (have your attorney read it 1rst before signing) they claim 5 yr warranty. but contract says different story. As they told me …. (we are not used to the customers reading the contract). Dah… | once they get your $$ you better hang on and pray . the contract calls for NO REFUNDS AFTER 72 HOURS!! | if they break anything at your home they wont cover the costs | if you do decide to use them (not recommended) you better take some time off work to watch over there shoulders. | the job may not turn out the way you expected it too.
