The critical reviews

The one and two-star reviews, first. These are what a star average hides, and they are the reason this page exists.

    Gentleman picked the time, no showed nor called prior. Didn’t answer call when late. Called an hour later proposing a different time, no thanks. If you can’t be on time or responsive for a quote, why on earth would I pick you for a project when actual money is involved? Reliability is very important! I do not recommend.

    Do NOT hire this company. They are completely unprofessional. They are unorganized. They will not show up for scheduled appointments. They are completely uncommunicative and unapologetic. If you value your time and your money, hire any other company.

    This company exhibits HIGHLY questionable ethics in their business dealings, and I wish there were an option for me to leave ZERO STARS. They were contracted to replace a roof on a rental property of mine, and one of their workers drove a nail into a water line, puncturing it and causing many thousands of dollars in damage (see photo of punctured pipe and select photos of water damage caused by THEIR mistake). They refused to accept responsibility for the incident, and my insurance company had to assume the expenses. One of their managers name Rick was rude and pushy when dealing with the matter, even entering the property WITHOUT permission, thus frightening the tenant. In no what whatsoever can I recommend anyone to enlist the services of this company. There are many other construction services in the San Diego area to consult. Skip these folks!

    JG Construction did an exceptional job on my project. Their team was professional, reliable, and easy to work with from start to finish. They showed up on time, communicated clearly, and delivered high‑quality workmanship that exceeded my expectations. You can tell they take pride in what they do — the attention to detail and the smooth, efficient process really stood out. I highly recommend JG Construction for anyone looking for skilled, dependable construction work.

What JG Construction Services says about itself

Taken from the business’s own website. We have not checked any of it. These are quotes, not credentials — a roofer writing “licensed and insured” on their homepage is not evidence that they are.

Where this page comes from

Every figure above is Google’s, captured on 24 September 2026. The star average and the 9 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 9, of which 7 have any text — and it is not everything Google shows.

Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.

There is not much data on JG Construction Services. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
