GDO CONSTRUCTION INC

Oswaldo and company are a pleasure to work with, from start to finish. New roof installed 1 year ago. Looks good as new. Reasonably priced and excellent workmanship. Cleaned our eves troughs while up there too! Great cleanup around house too. Have already recommended them and they were also very pleased. Will continue to recommend GDO Construction Inc.

I would definitely recommend GDO construction to anyone who needs to replace or repair their roof. Oswaldo and his crew very professional job on time fast. They did a great job and site was clean.

Oswaldo and his assistant replaced the shingles on our garage roof. It was a pleasure working with them, and they did a great job. The site was left spotless, and we are very pleased with the work.

Oswald was a pleasure to work with Gave me fair estimate work was done in timely manner very neat and professional

Oswaldo and Partner were very professional, courteous and communicated with me throughout the process. Material use was applied properly and end product looked excellent.

Spring 2020 - I hired GDO to replace the roof on my house; this consisted of 2 flat roof areas, and a small shingled roof section.
GDO did the work quickly (3 days). The workers were polite, and they cleaned up well at the end of the job. The quality of the job looks good.
GDO was recommended to me by a neighbour, and I would also recommended them.
My only complaint was when the work team left lunch leftovers on the roof overnight (between work days). Racoons got into this and made a mess. I commented on this the next day, and the crew cleaned up the garbage immediately.

Really good job very honest people
Job was done in a proper time manners
With a very satisfactory finish

Great workmanship very friendly job done on time and would use this company over and over again. I would recommend this company for any roof repairs or replacement top-notch work.

Oswaldo from GDO was an extremely professional and ambitous hard working young man. He was on time, did an excellent professional job preparation/Clean-up & had everything required to do a very good job.
Look no further, I tried them all, this is your guy. Also good pricing.
