They did a very good job. The price was reasonable. Zak is great to deal with.

After obtaining estimates from 12 firms recommended by Washington Checkbook, Angie's List, and the Better Business Bureau, we selected Alco Products Company due to the ratings, reviews, quality of the components they would be installing (they installed Simonton Energy Star Windows as recommended by J. D. Powers and Associates), and the willingness of the firm's owner, manager, and estimator Zak Kreisman to work with us, explaining the issues, and doing any problem solving as we moved throughout the process. The work done was outstanding. The flexibility of the firm was impressive, as was their concern about our satisfaction with each level and stage of the work. We strongly recommend this firm, who also did excellent roofing, gutter installation, coverage of house time with vinyl soffit and aluminum trim, repair work on the house interior, etc. The cost of this job was almost $25,000 less then several of the other firms who estimated. We are delighted with the completed project, which leaves us with very little future maintenance.

Zack, the proprietor, is an affable guy and seemed as interested in making us happy as in collecting his payment. Got 13 Andersen 400-series wood-frame windows installed in our old house, and the old windows removed, with lead precautions observed, in 2 days flat
