"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."

The House Next Door is one of the top remodeling companies serving the greater Los Angeles metro area, San Bernardino County, Orange County and more. We are licensed and insured. We guarantee excellent customer service and quality workmanship with every job we do. We offer a wide range of services that include room additions, kitchen and bathroom remodels, patios and decks. 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."

"We hired Joe and his team to handle our primary bathroom remodel and are very pleased only a few days into the work. While our bathroom is on the small side, in order to get what we want, it requires complete demolition and all appropriate re-configuration so it is a substantial project. In our initial consultation, Joe provided great space-efficient ideas and helpful suggestions for where to shop for the items we'd need. He has been extremely communicative and responsive which we greatly appreciate, as that can be hard to come by. So far his team has been quick and efficient and is meeting our expectations in terms of the daily schedule and progress.

Basement Waterproofing questions, answered by experts

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.
