"He hired Tom Harrop to install kitchen cabinets and a heater under the kitchen sink, vinal flooring, plastering in a small area, add ceiling lighting and a shiplap ceiling. Once the work was done I asked Tom to do a walk through and he refused saying he stood behind his empoyees work. Here are the PROs and CONs. PROs: 1.) work was completed in a timely fashion 2) they did a beautiful job on the shiplap ceiling and lighting. CONs: 1) The brand new white cabinets had some nicks requiring paint touch up. 2) Terrible job on the floors! Uneven spots, lengths are uneven at the edges, gaps showing, no finish work. Terrible job!! 3) plastering looks like it wasn't even done! And there is some peeling of paint on the plaster job. Terrible job!!! 4) we were promised and paid for an under the kitchen sink heater which we never received. Called multiple times with no response. Lesson learned, will never use Tom Harrop again!!"

Rick grew up in a family of hard working contractors, and has been learning the skills of the trade since a very young age. He brings to the table a high level of expertise that is often hard to come by, and will always take the time to get the job done right.

"Rick was very responsive at first and eager to get started on my bathroom remodel job for one of my apartments. He is commended for having to respond to quote request fast. I decided to give him a chance to do a good job before handing a bigger jobs for my other properties. Before the work started, I emphasized that the dust control and cleanup was very, very important to me. The job involved lots of demolition work inside the apartment - naturally, there will be lots of dust. The apartment is currently occupied and has lots of furniture, computers and audio equipment that I wanted to protect. I thought he and his workers were communicated this request. I even offered the use of dust control fan and Zip Wall to isolate the work area but he said he will be fine without them. Once the job started, I was away for one week to take care of my family. When I returned, I discovered that the door to the adjacent room was left open. That is my office with all the equipment and important papers. They left their construction material and equipment in this room. I was horrified that there are fine dust everywhere - on my printer, computer peripherals, furniture. I brought this issue up with Rick. Nothing happened. The worst part was that the job was declared done and I paid the service in full - They never returned to clean up and pickup the equipment. After almost a whole month, the supply and equipment is still there. I had to spend extra time cleaning up after their mess. Very unprofessional. Lessons learned. Do not pay the balance until all the cleaning is done and all the equipment removed. I expect the clean up and dust control to be a part of the job. I also repeatedly asked or professionally prepared invoices with vendor name and address, job details and the most important of all, the invoice number - all of these essential information is important to keep track of expenses for my projects. The SMS texts message and e-mail messages were not appropriate for this purpose. I explained to Rick that my CPA requires them many times. I even sent him a sample invoice and quote in Microsoft Word template - he never understood what I was asking. He is a nice guy, but not a good project manager or competent business person. The work was done, however, the work quality is fair to good - I had to go back and correct some sloppy work. Lacking attention to details and follow up bothered me. The biggest issues is the lack of clean up and keeping the worksite cleans so he and his crew gets an F. I do not think I will be hiring his company in my future projects."

"Watch out, different employees have us very different estimates. One was honest and one tried to way overprice our roofing project. Also during the installation they tried to skip replacing plywood as we’d agreed upon without discussing with us first. Luckily my husband was home and caught the mistake. There were definitely some good things too, the knowledge and quality of materials was excellent. They got our entire project done in one day and worked very hard."

"I recommend this wonderful company without any hesitation. I first contacted Wood Trades LLC seeking a deck quote in September 2024, and John and Karin came out the very next day. From day one, John and Karin provided impeccable service. I cannot say enough wonderful things about their communication, transparency, honestly, and reliability. All current insurance/contractor licenses were provided up front, and any change in cost was documented through clear contracts. In addition, they patiently navigated me through a difficult permitting process from start to finish. Once the work was started, I had a gorgeous new deck in just over one week. I cannot thank this company enough for gaining, and more importantly, maintaining my trust through this project. I certainly look forward to working with Wood Trades again, and highly recommend their services to anyone seeking high quality results from a wonderful company. Exceeded expectations!"

FAQs for basement remodeling projects in Portsmouth, RI

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
