We can install energy-efficient windows and doors, offer roofing services and much, much more!

"To Whom It May Concern: It has now been well over three years and our kitchen remodel has never been completed. We have not been contacted in over 2 years regarding the completion. This remodel has been LESS than satisfactory. Listed below are our grievances: 8/31/15 - We discussed with the salesman, Ron, what we wanted in the kitchen and the price we could afford. He eventually agreed and we asked if he needed to see the electrical box or anything else. He did not. 9/3/15 – After the kitchen had been demolished and $5500.00 had been collected from us, Ron finally looked in the electrical panel box and decided an additional $6250.00 would be needed to upgrade the panel, install LED lights, which he had told us weren’t necessary, and to put copper pipes under the sink (which already had copper pipes). He refused to continue the work without an immediate payment of an additional $5000.00. 9/4/15 We arrived home on that Friday night to find chicken bones on the floor of our demolished kitchen and empty beer bottles in addition to garbage, paint, plaster, tools and more chicken bones scattered all over our driveway and backyard. (Pictures enclosed-#1) We called the company and were told they would come out the next day to clean it up and haul away the trash. Instead, they moved the trash to the side of the driveway, leaned it against our new redwood fence, and it remained there for 4 weeks. (see enclosed picture #2) - The choice of cabinets had to be done by text because THND had nothing to show us. They were then put in without approval and they were, in many cases, either wrong or missing. - A cabinet was place directly touching the stove, a fire hazard. It would not have been corrected had the “city inspector” not pointed it out. (see enclosed picture #3). - The awful molding at the top of the cupboards, which in many cases doesn’t fit, was not a choice, it just showed up. And it started separating from the ceiling 3 months into the remodel, and had to be re-caulked. - The painting was done by a very inexperienced painter who didn’t even have a ladder. He stood on two paint buckets to paint near the ceiling. - THND must not own any ladders or buckets because the men used ours, covering them with stucco and paint, and ruining a large bucket. - The light fixtures were completely closed BEFORE the inspector came. He was NOT pleased. Everything had to be opened up again for inspection. - Rather than move electrical outlets, notches were cut into the backsplash to accommodate plugs – a very shoddy and amateurish job. (see enclosed picture #4) - An outlet was placed under the sink next to a leaking pipe. Again, the inspector saw it and saved us from possible disaster. - After the installation of the $5250.00 new electrical box, our brand new stucco was repaired so fast and poorly that it didn’t begin to match the surrounding stucco in texture or color. We had to wait TWO MONTHS for a correction and a big mess was left on the steps and cement underneath. - During a heavy rainfall, a leak in the bathroom ceiling, right next to the newly installed venting fan/light exposed an uncovered electrical box with loose wires floating around. Alarmed at the shoddy work and danger of exposed, un-grounded wires, we called our own electrician to come and check the work done by your company. 2/24/16 – Our electrician opened the ceiling in the bathroom to look over the situation. He said it is illegal to hide a box in the ceiling as had been done. Plus, it hadn’t been grounded and the box had to be extended to bring it down to ceiling level. Since he had worked at this house in the past, he knew that the LED lights in the kitchen were new so he went up into the attic to see what else was going on electrically. He said there were two other boxes that had been covered up and weren’t grounded – one in the main kitchen and one in the laundry area. Since nothing had been grounded so far he decided to check the new plug by the stove and found the ground wires cut off and thus not connected. He had to take out the box, extend the wires and reconnect the whole thing. Along the way he noticed that the new electrical box outside had loose wires, disconnected wires and mislabeled circuits. As he was working on the plug by the stove he noticed that it was on the same circuit as the stove and the microwave – all labeled dishwasher. He said if we tried to run a toaster oven when the microwave was going we would blow the circuit. I’d be interested to know what the “dedicated” lines to the kitchen actually are. We paid an extra $4000.00 for them. We now had several holes in the ceiling that need to be re-plastered. The electrician said that if it had been done properly the boxes that were covered up would, instead, have been turned around and opened UP to the attic instead of burying them. As it is now, the boxes on the ceiling, even with decorative covers, are ugly and amateurish. 3/15/16 and 3/18/16 – your electricians returned to finish and check remaining work. Holes remained open in the ceiling of the kitchen, washer/dryer area and bathroom. An appointment to fix them was made and cancelled and then we never heard anything from THND again. 1/31/17 – A continuing leak in the bathroom ceiling, caused by the vent put into our new roof by THND, had to be repaired by our roof people. We paid for this. (see enclosed picture #5) 2/2017 – We had the holes in our kitchen, washer/dryer and bathroom ceilings repaired and painted. We paid for this. To say that we were disappointed with THND would be a gross understatement. We saved a very long time in order to be able to afford a kitchen remodel. We expected to be working with professionals but most of the work was at best, amateurish, and at worst, dangerously negligent."

FAQs for basement waterproofing projects in Norwalk, CA

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

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.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

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.
