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."

FAQs for addition to existing structure building service projects in Riverside, RI

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
