"This is a new review for Watertight Pro. This is my third time using this company. Again all I have are superlatives. I know I can count on Manny and his team to deliver great workmanship. I needed to have almost all of my inside walls, ceilings and trim painted. Also needed to have my house and rock wall power washed. And then while the job was happening, I had other issues I asked Manny to address if possible and he delivered on every problem I had. First off, most of the inside painting was done by George who is a magician. He is so proficeent and meticulous, the results were better than I could have hoped. He even painted our metal heating grates. Can't say enough about the great job he did. Manny and his team also did a super job power washing our Hardee board, which over the years had a lot of moss accumulating. He also power washed our rock wall and that came out great as well. The rock wall needed some masonry work and Mannys team also handled that,. came out fantastic. I had a porch door that wouldn't open. Manny took the trim off (on the outside), releveled the door and it now opens closes as it should. We had another door that would stick, i mentioned it and next thing it was fixed by George. Our deck needed to be painted as well and they sanded/scraped and put 2 new coats on and it looks great. They also fixed some trim on the deck that had come loose. Finally, our shed had algae all over its roof and they power washed that as well. I could go on and on. My front stoop needed some masonry work and Manny handled that himself and did a great job. What I love about Watertight Pro is once they start a job, they stay with it til completed. They were here 9 days in a row, including 2 weekends. The work I had done would have normally required multiple companies to complete. Quality work at a fair price. They have an A plus plus rating from me. If needed I will use them again for sure."

"One of the worst companies I have EVER dealt with in my life. Nothing but runaround, lies, and lack of accountability. They will tell you something over the phone, then when you follow-up, they will magically lose all records of prior conversations. I was told replacement windows would be ordered in June 2024 - never ordered. In January, ordered correctly with 4-6 week expedited delivery time quoted. Now in Feb, was told the windows would not be ready until end of March (total of nearly 11 weeks since order). Magically, they have no record of quoting me 4-6 weeks, though I have email records saying otherwise. Just a miserable company to do business with, would never recommend to any homeowner."

Established in 1976, All Under One Roof has the experience and expertise to get the job done right the first time. Our skilled professionals use only the finest tools and materials for your residential or commercial project. We guarantee our work and your satisfaction.

"Overall it went great. John was down quickly after I first contacted him. He came out in person to give me information and confirm the online measurements. Between meeting him, reading the reviews online, and the impeccable warranty I felt very comfortable choosing him (the price was in the middle of the other quotes I got). The whole process took 3 real long days. Obviously it is loud and disruptive while they are working... but you only need a new roof once. I would suggest not parking in your driveway as there are a lot of people and trucks. At the end they cleaned up very nicely. They are a legit roofing company so they pull permits. Overall I am quite please for the job, cost, time etc."

Home energy audit services FAQs

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
