"They had done roof repairs for us in the past, so we hired them to do painting (inside & outside), stucco work, refinished our front door and tiled a bathroom. They always showed up on time every morning (it was a 10 day job). They worked throughout the day. They were great at making sure to seal off the work areas so they didn’t make a big mess & they cleaned up after themselves. Friendly crew, felt comfortable having them in my house. Excellent work results."

"We waited to review our project 1 year after completion to be sure that all was well. We are very pleased with the final result. Our only mishap was having miscommunications with B&B when we requested follow up 4 months after project completion – our issues were resolved with a factory representative. No hard feelings. How It Went- Workers were professional and competent. Building on an existing slab is extremely challenging – because the slab slopes away and down from the house – 2 angles that need to be countered when leveling windows and doors etc. When corrective rework was needed (to compensate for a 2 inch site deviation) the team didn’t hesitate and B&B came up with an excellent solution. We retained the exterior stucco exterior of our house for the room and they finished the wall beautifully – it required a lot of fine and patient work. We asked for an 18 inch deep exterior pad – which accommodates a doormat and our foot print. It was done this way – although there was initial push back on this request. We also involved our own electrician, who is familiar with this old house – and we came up with an elegant solution to connect to our home. After project closure, we delayed evaluation until things settled out. Over the next few months, some of the sliding windows became increasingly difficult to open and close – and during an extremely fierce and long rainstorm we experienced a leak coming from one corner of the enclosure. We immediately spoke with B&B. With miscommunications with B&B, we resolved our issues with a factory representative in a single short visit: they added weep holes to the exterior, caulked, replaced a window roller and adjusted windows and the screen doors. We are very pleased with the final result. And so are our kitties."

"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

Excavating FAQs, answered by experts

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.
