"We have a strange leak in our basement that recurs every time it rains. To figure out the potential source, we called Alpha Structural, and the entire team was outstanding from the get-go. Lisa Hunter first took a detailed account of and keen interest in our situation, and then Gary Coffing came to inspect our house. Gary possesses an incredible wealth of knowledge about foundation and structural integrity, and gave us a very fair assessment of what might be happening, and what we could and should try first. Rather than make a hard sell to engage Alpha in a major investigation, he suggested we first try a few simpler solutions, including fixing the grading of our soil leading to the basement as well as our gutters. Perhaps this won't work and perhaps it will, but the point is he gave us a full account of what may be happening and a number of specific things to try before pulling the trigger on a major structural ordeal. A HUGE thank you to Gary and the whole team. We hope it doesn't come to it, but if we do need to go down the route of major structural work, we will absolutely call you again."

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote.  Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"Let me start by saying that US Home Developers hires people with good intentions, especially Regev whom we are forever grateful to for helping us look for our dog when he went missing, but their work product is substandard.  (Let the photos we post be the evidence.)

Our bathrooms were actually completed in March 2013, but we didn't post any reviews because we come from the old school of "If you have nothing good to say, then don't say it".  BUT, after our SECOND warranty call with them today, we just couldn't remain silent.

This review is on the warranty call we made to repair our master bath ceramic undermount sinks that are separating from the granite countertops.  We called US Home Developers 2 wks ago about the sinks drooping.  Eli, our original project manager, called back and came out promptly the next morning to examine the problem.  Now, Eli is very courteous and professional, always taking off his shoes before coming into the house.  Eli agreed the sinks were drooping as the silicone had major gaps/cracks and you can clearly see the sinks rise and fall when you push them up from underneath.  Eli agreed to fix themand told us to let him know when we were ready (we originally wanted replace a couple cracked shower tiles caused by the recent earthquake but decided to hold off thus the delay in scheduling.)  Eli said they will put wood underneath as additional support and re-silicone all sinks in master bath and guest bath (sink in guest bath was never siliconed correctly; there are huge gaps where they failed to continuously apply the sealant.)

Eli promised someone would be here today but couldn't tell us the time until we had to nudge him further and let him know that nobody was going to be home to open the door unless we have a specific time.  Everyone has things to do and we can't sit around all day waiting, which we did before when one of their plumbers was supposed to show but didn't.

 Around 8 am, 1 worker showed up.  All he knew was that he was suppose to fix sinks.  We had to show him the sinks and describe the work that needed to be done. He didn't believe the sinks were drooping until we physically showed him, claiming Eli only informed him to "re-caulk" the sinks.  Really?  I don't like wasting my time or yours, but when there's a problem, there's a problem.  Why would we have you over if there wasn't?

Then the work began, sawing wood, hammering, and drilling, and he was done within an hour and a half.  The worker then cleaned up quickly and told us he was done.  When he said he "caulked" the sink, I told him Eli said silicone.  His reply was "Eli told me to caulk".   We're going to assume he meant silicone caulk, but to be honest, we still don't know whether we have caulk or silicone between our sinks and whether it waterproofs or not. I wasn't going to argue this with him, and away he went while I was upstairs inspecting the work.  He cleaned up and left within 5 mins so that left very little time to review his work.  Needless to say, after he left, that's when I discovered all sorts of problems with the sinks.

First, he didn't remove the old silicone before applying the new caulking.  We're hoping the new caulk will bond to the old silicone but we're not going to hold our breath on that one.  God forbid it separates. My husband has decided to just reseal it himself as we are not letting them set foot in our bathrooms ever again.  UPDATE: When I went to clean the sinks 2 nights later, I discovered the "caulk" isn't even waterproof.  It comes off when you simply rub it with your fingers (like eraser bits) or simply washes away with water.

Next, I peeked under the sinks and NOT to my surprise, the posted photos will show you what I discovered.  There were 2 strips of wood nailed into the plywood under each sink.  On 3 of them, the wood is chipped or cracked from driving in the nails.  On 1 of them, there are so many screws, some of them even missed the wood.  My initial instinct was that they were there to hold in the wood until I realized they don't because there is a gap between the nail and wood.  I then realized those nails are there because they had gotten stuck in the wood and the worker didn't bother removing them.  So now the plywood underneath our sinks have several needless nails & holes.  Not that anyone is going to look under our sinks, but we don't want to have so many holes in the plywood that is holding up the granite countertop; if the plywood is compromised, clearly they can't do their job.

Then, out of curiosity, I stuck my hand between the wood strip and the sink.  Again, not to my surprise, what do I discover? There is a gap.  Enough so that I can stick my entire hand in there.  And not a single piece of wood between the wood strip and sink.  What does that mean?  The wood is there for appearance; there remains nothing to support my sinks.

Are we angry, frustrated, disappointed, and appalled?  You bet.  But are we surprised? No.  This isn't our first warranty call.  The first time we had to call them because we were having cracks in our tiled shower grout.  Turns out, they used regular grout for the joints between the shower walls and floor instead of silicone grout to allow for movement like the code calls for.  They "fixed" it using premixed grout, the type you're not suppose to use in showers according to all the online research, contractor forums, and contractors I've talked to.  In honesty though, we haven't had any additional cracks in the grout since then.  How long they'll hold up or whether water's penetrating through them, we imagine we won't know for a couple years until it gets really bad.

We also imagine US Home Developers will post a response to our review and if they hold up to their Angie's List status, reach out to try and remedy the situation.  If they're professional, they will admit their mistakes in their response.  If they're not, the response will likely state that we were difficult homeowners to work with, they did a lot of work for our bathrooms beyond contracted scope, that they went out of their way and we're ungrateful, that the work they've done is according to industry standards, that we're lying/exaggerating, or a myriad of other excuses or explanations.  They may even claim we don't know much about construction.  As attorneys who have practiced construction and real estate litigation for at least half of the last decade, our experience, knowledge, and careers would demonstrate otherwise.

Although we have another year of warranty left, you bet we will not  be availing ourselves to it.  We interviewed several contractors for our bathrooms and hired US Home Developers because they were highly rated on Angie's List.  When problems first came up, we thought it was because we had a bad crew.  But after 3 different interactions with them including 2 warranty calls, we're resigned to believe that their work is substandard at best.  They had chance after chance to redeem themselves, but at each turn, we were only met with more disappointment and problems to address.  We really wanted to leave a glowing review for them, especially Regev who was always more than helpful and patient, but we just find it difficult to do so after all the negative impressions they've left behind.

NOTE: The metal clips seen in the photos were put in when they originally put in the sinks.  That was the only mechanical system put in to support the sinks when they were installed."

Basement Waterproofing questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

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

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
