"Harrop & Son Remodeling is by far the best construction company I have had the pleasure of hiring. We were hiring for a complete basement remodel and the owner, Tom, called immediately after submitting our inquiry to Home Advisor. Harrop & Son was 1 of 3 companies to give us a quote and they landed well ahead of the competition. Tom was professional, very detailed in his quote, and was extremely knowledgeable about his craft. Honesty was a big reason I hired Harrop & Son. While the competition was ridiculously over pricing the job and looking to take advantage, Tom came in and provided me with an honest quote that was half the price of the competition but afforded double the square footage and a full bathroom, which had been out of the question for the other companies. It was clear that Tom really cared about getting you excellent value for your money. They started right on time and they blew me away with how professional and courteous they were from day 1. They made excellent use of their time and I never saw any of the crew not working. The Foreman, Rick, was excellent and I had complete confidence that when Tom was off site, Rick had everything under control. From the owner down to the sub contractors, everyone was extremely professional and did excellent work. The work completed by Harrop & Son is beyond exceptional. They truly are masters of their craft. They were very detailed in their work and anything they touched had maximum effort put into it. Very little changes were made throughout the process, but for the ones that were, Tom was extremely welcoming and was always 1 step ahead. The whole remodel was kept within the quoted price and the work completed far exceeded my expectations. We couldn't be happier with Tom, his crew, and the remodel they completed for us. I would not hesitate to recommend Harrop & Son Remodeling to anyone I come across looking for home renovations. We have a few other home renovations planned for the near future and I will not hesitate to contact Tom to have them back."

Basement Remodel FAQs, answered by experts

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

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.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.
