"OUR HOUSE IS GORGEOUS!!!!!!
My first interaction was with the young lady who answered the phone & she was extremely pleasant. We set  up an appointment for the Designer to come out & he was prompt & courteous. He gave us a lot of information about products, the company & time frames for our projects. He also explained that he was going to draw the kitchen & why. We set a second appointment for him to come back. When he returned, he had everything ready for us & to save a substantial amount of money, we started the project. This was the best decision we have made in a long time...especially on this big of a purchase, as we have been saving for a long time for this. (We had obviously done our research on Jericho & trusted their abilities)
The project began as expected...and although there were a couple of short delays(to be expected with a remodel) we watched our kitchen & baths be transformed in to amazing rooms!
We absolutely love the finished product & Mike (our project manager) did a fantastic job coordinating all of the installers with each project & keeping us informed. The quality of products are exceptional...just as we expected. We truly are happy with this project & process. We have done other remodels in the past with other companies (and the projects were much smaller) and they were not good experiences.
Thank you Jericho family. We will refer you to our friends & family.

"The floor was changed from wooden slats to a ceramic tile that the contractor recommended.  The screen windows were changed out to full view custom casement windows and two new full-view doors.  A room-specific heating and air conditioning unit was also added.  The whole room was painted inside and out.
The people working on this job were fantastic--friendly, conscientious, and truly professional at their craft.  We do not hesitate to recommend this company for any remodel job.  In fact they are just starting work on the basement."

"We had reached a point where our master bathroom couldn't be used--the shower tile was falling apart, the toilet was leaking, we could see water damage to exterior of house was spreading, and the door from the bedroom to small deck wouldn't close. We gave up using our toilet/shower area and were instead sharing the main bathroom with two teenagers.  Our job was more about "repair" than the fun of "remodeling." 
We contacted Ethos, and we couldn't ask for a better contractor than David Gurwell.  He was honest, easygoing and always kept our budget in mind. He offered suggestions to save money (i.e., repairing toilet vs replacing), and we relied on David's opinion of products and businesses to help us make decisions about materials.  We wanted to make sure we were using quality products at a price we could afford.  David was also very patient with us, as we don't have much in the way of decorating skills (I once repainted a bathroom 3 times before I got to a color I liked).  We discussed tile vs Onyx for the shower, and while I like the look of tile, I really liked the idea of Onyx walls with only a couple seams (we have trouble with mold/mildew).  Had never heard of Onyx before, so appreciated David going over pros/cons.  We were originally going to use Onyx for the sink countertop too, but when I told David I just wasn't sure about it after seeing the displays at Home Depot & Lowe's, he helped us compare our other options.  We ended up with a high-grade granite remnant from Top Master (one of David's contacts).  We didn't spend much over what the Onyx would have cost, and we're very happy with the look of the granite. 
We felt comfortable with David, his son Ben and Ben's assistant being in our home.  They were always on time, kept the work area neat and were nice to our dog Ava (she's a noisemaker!).  They kept us informed on the status of the project at the end of the day and what to expect next.  They were considerate of our crazy schedules and flexible with their hours. 
It's wonderful to have our master bathroom back, and now that we have a great contractor, we're ready to tackle a few more projects on the "repair" list.  We've already asked David to come back!

"I had a great experience with Dry Basement. The estimator Curtis was extremely knowledgeable, clean cut, friendly, and straight forward. He arrived right on time and got to work. He reviewed my situation with laser measuring equipment and had a written estimate for me on the spot. We agreed on a price for the work and scheduled my repair for their next available slot, three weeks later, on December 11, 2014. I received a call from their office staff two days before the scheduled work, to remind me of my appointment and their estimated arrival time. The crew of four guys showed up right on time and got straight to work. The foreman, Alvin, was great and worked just as hard as every other guy on the crew, and these were about the hardest working guys I've ever seen in my life. Everyone was super friendly (my Labrador retriever vetted each of them and approved). It was a wet, sloppy day outside, and they put plastic down on my carpeted floors and stairs to keep things tidy. They installed 10 u-channel braces in the basement to shore up my slightly bowing foundation (just under 2" of inward bowing), and secured it to 8 yards of concrete - that's 32,000 pounds worth - in the yard. The cracks inside were sealed with polyurethane. They finished the job in one day, as promised, and cleaned everything up when they were done. In fact my basement was cleaner when they left than when they showed up. I would definitely hire these guys again, though I don't plan on having to, since from the looks of things this house isn't going anywhere. HIGHLY recommended."

Basement Remodel FAQs, answered by experts

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.
