"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

"I hired the company to do a make ready [clean up & prep] on a single apartment in a building which I own in the  town where I live. I needed the property to be cleaned up so I could rent it again.  I have been a landlord for over 20 years & hadn't found a vacated property in such a mess in all my years. They did the complete interior clean-up which took about five hours. And, the complete prep of the property. they took out all the trash & junk, and cleaned up all debris left in the yard. They did such a great job with that I decided to use them for the yard maintenance also. They cleaned all my flowerbeds & got them ready for spring, placed mulch & trimmed the shrubs and flowering trees. On the inside they made everything look brand new! Cleaning the walls, painting, cleaned the carpets & stripped & polished the wood floors...making them look brand new. The appliances that stayed were cleaned inside & out. They even remembered to get all the light fixtures clean for me. Dusted all window seals & doorways. Shine mopped all they tile floors. To top it all off they even gave the bathrooms a fresh clean look by putting a new caulk seal around the tubs, sinks & shower...which gave the bathrooms a fresh face. All in all I found it to be a very stress free pleasant experience. And, I will definitely call on them for the next project because if they could do so well with a nightmare like that I'm sure the less difficult will be equally affordable and easily handled. Everything just looked so nice when they were finished. Thanks, Green Earth

Basement Remodel FAQs, answered by experts

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.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.
