Work Description: Needed quote for project pricing.

Comments: Had callback from company within 5 minutes and got a real person with just the information I needed. Very efficient.



Work Description: replaced a damaged bottom section of my overhead garage door. in addition the existing doors were fine tuned, pulleys replaced and all moving parts lubricated.

Comments: Gary was available 4 hours after my call. He arrived with the almost exact match for my door and replaced everything with professionalism and care. His pricing was less than i expected and his extra work was very resonable.

Work Description: I just needed another remote control for the overhead garage door so I just acquired it without any problem.

Comments: Very personable people to do business with for any issue needed.

Work Description: Garage door not operating properly

Work Description: Two overhead doors were serviced. they were in need of a) wheel bearings b) reprogramming of remote controls c) releasing one motor that was 'frozen

Comments: All work was performed efficiently in one hour

Work Description: Gary put in a new pair of a garage door receiver and transmitter remote very punctually last Sat. morning. Before leaving he told me he noticed the g. door he was working had no rubber weather stripping at the bottom so I hired him to put it in next Sat. Just after he left went out put my car back into the garage. But when I tried to close the door using the botton besides the house door in did not work. The remote worked very well however. So I called his main number and he said he would fix it next Sat. when he puts in the strip next Sat. Ron Vallon

Comments: Probably just a plain mistake that he just forgot to test the button to open the door. He said something about the button being disconnected and had to reconnect it. Well I disconnected when I took off the old receiver to get a good look at the model and serial on it thinking that it would have to be reconnected during the repair?. I noticed he was talking on his cell phone about his next job in Braintree while he was working on my repair. So a busy man that just missed a step during his current repair. No problem since it will be repaired and if he's been thorough in the past and its not habitual. Ron Vallon

Work Description: Opener would just hum and not open. Gary said he would be here next morning and arrived at 9AM.. He also replaced two springs which were on the verge of breaking..

Work Description: Two overhead garage doors were replaced with Protege (R-12) units and door openers purchased previously) were installed for us as well.

Comments: The sales rep, Gary, was extremely nice and helpful. The two people who did the installation answered all my questions and did good and clean work. I wholly recommend this outfit for future customers.

Work Description: Replaced torsion springs on garage door.

Comments: Very impressed with the quick response time and excellent service. The garage door operates better than it did. The guys also took the time to explain what was wrong with the door, and suggested how to maintain the door to help lengthen its life. Highly Recommend...
