"I cannot say enough about these guys. Their prices were reasonable and about average compared to other companies. The owner, Dave was great to work with, he kept us updated on a daily basis, and was there every morning to look things over and help get the guys set up. The workers were there at 7 am every day. Work was done well within the given timeframe. Everything was left clean each day. They built a bedroom in our basement, and gutted and remodeled a bathroom, we couldn’t be happier with both projects. Very professional, highly recommend."

"Shawn and the crew tended to our every need with precision and detail. A superb job! We had basement repairs, LR/DR repairs and a full kitchen remodel. We were nervous about the kitchen but Shawn, Manny the PM, Carlos the electrician, Ray the cabinet master, & the rest of the crew were extremely accommodating and paid attention to every detail. The kitchen came out amazing along with the rest of the house. Some contractors cut corners , we’ve experienced it, but East End really does quality work. 5 stars for sure. Thank you guys!"

Customers say: True professional

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"I hired Loja Renovations to assembly a number of furniture I bought online that was very difficult to put together. They came and quickly assembled them with ease. They're very skilled and efficient. Apart from the reasonable cost, I was particularly impressed with their professionalism, their show of care for the customer and their respectful attitude. I definitely plan to use them again."

"Javier painted my 25x10 deck and ceiling above it. He was prompt onetime and did a good job. There was a mix up in the color of the paint which was not his fault. I paid in full for the work. He offered to stop back and give the deck another coat with the right color. He has not returned yet but hope he does. Nice man and good work."

Basement Remodel FAQs, answered by experts

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%.

Yes, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.
