"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

"I can't recommend IND Construction highly enough, especially Project Manager Dorel and Crew Chief Javier! After experiencing water damage in my bathroom from the unit above, I decided to not only restore it but also take the opportunity to upgrade the space. This included new drywall (ceiling too!), intricate tile work, additional lighting, a heater fan, and a custom paint palette. What truly set IND Construction apart was their exceptional service. Dorel and Javier were masters of consistent communication, keeping me informed every step of the way. Their attentiveness to detail was incredible – I'd often inspect the day's work, thinking of a small touch-up, only to find they had already identified and addressed it! I was also thoroughly impressed with their good general decision-making. In instances where I hadn't provided specific input, their experience shone through in the quality choices they made for the build-out. Furthermore, whenever I did have feedback or requested changes, they were incredibly responsive and agreeable, always ensuring my needs were met. As a wonderful bonus, they were fantastic with my dog, Maggie. She can be a bit barky and protective, but she absolutely warmed up to them and enjoyed their company."

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"I got their name from a friend who was very happy with their kitchen remodel. I hired them to remodel a rental home. They ripped out the entire kitchen, removed two sliders and closed the opening and added large windows, replaced the entire floor throughout the house, remodeled the 2 bathrooms and fixed a leak in the roof that turned out to be a bigger fix than a quick patch. I was very happy with the entire job. David handled everything and was very communicative throughout the entire project. I travel a large amount for work and my biggest concern was to have to be involved in the project. Besides going to that has to check on the process the took care of the entire thing including receiving all of the new appliances. If you want a stress free , great job I would hire them in a heart beat."

"Gino with Imperial Remodeling was fantastic. He is professional, an excellent communicator, does quality work, and is also just a really nice guy. As a woman, I didn’t want to work with someone who would be dismissive toward me or only want to deal with my husband — and that was never an issue. I’ve heard countless stories of contractors being impossible to reach and not showing up when they said they would. That was never the case with Gino. There wasn’t a single time when Gino or his crew weren’t exactly where they said they would be, exactly when they said they’d be there. He always made himself available to answer any questions we had. He does not cut corners. I stopped by the house when they were installing the hardwood floors, and he was personally going through the boxes, pulling out the best-looking pieces to use in the living areas and saving the pieces with less attractive color variations for closets or under cabinets. That’s how much care he puts into his projects. Any issue or hiccup we encountered, he made it right. He even finished ahead of schedule. Gino takes so much pride in his work and truly wants his customers to be happy. We cannot recommend him enough."

FAQs for basement leak repair projects in Altadena, CA
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
