Fabulous job . We have 20 large nonstandard windows and a brick house . So far we have installed 14 with 6 more ordered . Our contractor is an absolute craftsman of the highest caliber . He is a window genius with years and years of experience . This is the company to use if you want quality unparalleled work . If you want a job and windows that will leak and will be inadequately installed with tubes and tubes of caulk , then go with the company where everybody wears a logo t shirt and has completed their 2 week course on how to install a window . .you will be so sorry . The horror stories I have heard . This contractor goes word of mouth, has a small business and is not spending millions in advertising .
He is a true craftsman , reliable and does not overbook . Your job will be completed in time and you will LOVE your new windows. .your home will be quieter and hold heat and cool infinitely better . They also install PERFECT DOORS . I tried but don’t have enough words to express our immense satisfaction and gratitude .
