As a member of the heavy labor union for over 35 years, I can appreciate an installation that goes smoothly. The construction crew from Stanley were absolutely professional on the job site and were practically choreographed in their actions. Each man had his job and no one got underfoot of anyone else. The crew was so efficient, they got the job done in 1/2 day less than they told me it might take.I almost forgot the windows look great too!. They were measured and specially constructed by Stanley Contracting so they were a perfect fit, and our original finished frames and sills could remain. We didn’t have to refinish at all, which was good news for me.
