Amanda provided receipts and timesheets regularly. - They have superb attention to detail.

"Carlos has been helping us with some framing items we needed to take care of in the midst of a renovation of our 1926 home. He has proved to be reliable, efficient, and fair in his pricing, as well as very pleasant to work with. I am keeping his number as I will definitely work with him again in the future and recommend him to anyone needing framing or deck building services."

"I love love my new deck. It is now better than when it was originally built. The stairs were rotting out and new stairs replaced them. Half of the flooring was replaced as well as top of railing. All the folks I dealt with were very professional, friendly and easy to work with. The person who gave the bid was great. The guys that built the deck knew what they were doing. The guy that picked up the old parts was great also. I am very happy with Interbay Construction. Thank you very much!"

"Gil did an amazing job of figuring out exactly what I needed, and he hired an amazing crew to get it done. This is by far the best home renovation experience I've ever had. Gil and Oliver both were very thorough in figuring out what needed to be done, and every step of the way if there was ever any ambiguity, they asked questions and came up with great solutions for everything that came up. I have never before had such a good experience with a home renovation, and I wish all contractors were as good as them. My project was fairly involved, with a complete renovation of my kitchen, dining room, and laundry room, and yet the whole process took under a month to get done, and it was done right the first time. I wholeheartedly recommend Your Home Builders. No complaints at all."

"New Home Solutions is a Design+build firm and since we were unsure of the choices we needed to make for our kitchen remodel, we engaged New Home Solutions' design services. Marybeth was handling the design aspects and she did an excellent job with her recommendations. She helped us pick out our counter-tops, our back-splash tile, figure out our cabinet layout. She also worked with multiple vendors to give us an detailed breakdown of the estimates. She was responsive on email and made multiple store/home visits to ensure she understood and translated our needs to the estimate. Unfortunately due to vacation timing, we couldn't proceed with New Home Solutions' Build eventhough we were happy with the designs and the final estimate. Would totally recommend Marybeth's services."

Basement Remodel questions, answered by experts

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Project timelines vary significantly, typically from weeks to months, depending on design complexity and active permitting processes.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
