Diligent Remodeling replaced our windows, front door and French door off our deck. Overall they did an amazing job from start to finish. They lived up to their name (Diligent) through their professionalism and integrity from their office (Dani) to the field as Patrick made sure measuring was spot on. Kamil and his team (Sebastian, Krystiau, and Albert) were thorough & respectful of our home during the install. The owners Seth, Todd and Andrew assured us that we would be satisfied with the finished product and we are overjoyed with how transformed our home looks. Thanks Diligent for making our home beautiful. You deserve 10 stars and we highly recommend your company.
Response from the owner: Thank you Lashon for your glowing review! We're thrilled to hear that our team delivered such a professional and respectful service. Your satisfaction and recommendation mean everything to us. Looking forward to working with you again!
Todd, Seth and team were amazing! They replaced our roof, siding and gutters. The crews were on time, cleaned up and worked extremely hard each day. We were very pleased we chose Diligent and would recommend them to anyone! Thanks guys for your hard work making our house look amazing and ensuring our home is protected from the elements.
Response from the owner: Thank you so much for your wonderful review Mike! We're thrilled to hear that our team met your expectations with the roof, siding, and gutter replacement. Your recommendation means a lot to us. Thanks again for choosing Diligent!
Diligent Exterior Remodeling is absolutely amazing. The amount of attention they pay to detail and customer satisfaction is out of this world. Their crew was fast and efficient at installing 27 windows in my home and they made sure everything was perfect. I received calls and visits from DER while the installation was in progress to make sure everything was to my liking. These guys are amazing. Everything from pricing, quality, customer service and everything in between has been the best I’ve received. I’ve had many contractors and companies on my project and these guys have outdone all of them. I definitely recommend DER to anyone needing any services they provide. You will not be disappointed!!!

We're especially glad that our efficiency in installing your windows met your expectations. Your recommendation means a lot to us, and we look forward to serving you and others in the community with the same level of excellence. Thanks again for choosing DER!
Diligent did an excellent job for me! We replaced 19 windows in a 2010 townhouse because the seals had broken in the original single hung windows causing fogging between the glass panes. Seth Verderaime, the owner, was very knowledgeable about the product and process and had a good team of installers who finished the entire job in one day. Being the owner of a small company, I felt he took a personal interest in seeing that the job was done right. Delivery and installation was on schedule as promised. They measured all of the windows on two separate visits and everything fit perfectly. We installed the Providia windows. I would highly recommend these guys!
Response from the owner: Thank you so much for your kind words and for recommending us! We're thrilled to hear that you're satisfied with the new Providia windows and the work our team. Wishing you a wonderful holiday season filled with joy and warmth in your newly improved home. Happy holidays!
Just before the pandemic my husband ask a well know window replacement company for a quote. I looked at the quote and figured that it just wasn’t going to happen. This year in talking to quite a few neighbors Diligent Exterior Remodeling was highly recommended by each one of them. I had them give me a quote which was significantly less than the 1st quote by the other company. The quote was very reasonable. I was impressed with the timeline given. The crew that came out was awesome. They were polite, respectful and clean. They had completed the job in a day. I am love our new windows. We were so pleased we ordered a replacement front door. Different crew but just as polite. I highly recommend Diligent Exterior Remodeling.
Response from the owner: Thank you for choosing Diligent Exterior Remodeling and for taking the time to share your experience! We're thrilled to hear that our pricing, efficiency, and the professionalism of our crews met your expectations.

Diligent Exterior Remodeling just completed a flawless roof replacement for my parents, who are in their 80s. Their roof was old and had several layers of shingles; they were concerned it might fail in the next big storm. I recommended Diligent because I knew they'd treat my parents and their roof installation with the utmost care.Seth, Todd, and Andrew did everything they could to make the job smooth and professional. They were friendly and communicated when there were minor changes to the schedule. They helped my parents make a color/style selection, were in touch regularly, explained the process, and encouraged questions.It was a pleasure working with Diligent and I'd recommend them to anyone looking for exterior remodeling services.

Ok guys if you are looking for window compony that’s gonna waste 3+ hours of explaining that the windows they installed are the best and want thousands of dollars for it THEN THIS COMPANY IS NOT FOR YOU!!!!Those guys are the best because they made buying windows as simple as it can be, and also affordable!I met with both Andrew and Seth,Andrew came measured the windows,explained about the brand and gave me a quote for less then a hour!Seth came and double checked the measurements and told me as soon as they arrived (6-8 weeks),they will install them.After 8 weeks Seth came and knocked out the job for half a day😮. One of the windows end up being cracked due to shipping witch is not a problem because it’s covered,but overall wow!If we ever need any exterior work in our house i know that Andrew and Seth got my back!!!Thank you!

I had two windows replaced and siding replaced on the addition. My house was built in 1895 so there were additional challenges to these jobs. I appreciated the responsiveness and text communication to keep me updated on the process. This was not a large job as far as home improvement goes but they never treated the job as unimportant (which has happened with other contractors).
Response from the owner: It was a pleasure working with you Melissa! We appreciate the kind words and hope to work with you on any future projects!

No haggling, affordable pricing, they came out gave a quote for our roof and then I switched up and threw in the gutters and even that process was quick and affordable. They came out a week later to do the roof and gutters. The crew was polite, quick and very clean. Was super worried about debris and nails in the yard due to pets. They used a sweeper for my yard several times with a magnet. My house looks amazing! Can’t thank them enough their product is awesome my energy bill went down! Highly recommend them.
Response from the owner: Thank you Tammie, it was a pleasure working with you and you’re husband! We look forward to working with you on further projects!
We originally hired Diligent to install some vinyl windows last year, with the idea that we would replace another batch this year. Last year, as we talked, Seth mentioned that he was expanding to include siding replacement. We had cedar siding, and had been considering replacing it with vinyl. This year, we went all in and replaced the rest of the windows and replaced the cedar with insulated vinyl. We were very pleased with the products offered by Seth and Kevin for the jobs. We placed the order and we’re told that product shipment would be about 3 months. They kept in touch periodically during that time. Installation was impressive! The crew that did the siding worked long hours and did a very professional job with both the install and the clean up. They were very respectful of our personal property. The nine windows were replaced by Seth and Kevin personally, in half a days work. We appreciated that the people who gave us the estimate and did the selling were the same people who did the work. This is a company that is deserving of five stars!
Response from the owner: Thank you, Thomas, for taking the time to leave us a review! We're thrilled to hear that you had a great experience with Diligent and that we were able to meet your expectations with the vinyl window installation and siding replacement.

These guys are super nice and did an amazing job redoing my entire house exterior with stone and siding, replacing the gutters & downspouts, and installing stone on my retaining wall. We met several times to ensure it was exactly what I wanted. They followed up throughout all the projects and a couple times after completed to make sure I was happy.. All the neighbors have stopped by to compliment the transformation. We absolutely love the work they did.

I have zero complaints about Diligent Exterior Remodeling. Everyone I dealt with was great. Andrew was very knowledgeable with sales which made it easy to decide. Seth and Kevin were super efficient during the installation and there work was flawless. They were also very interactive with my 4 year old son who was following them around because he was curious about the tools and what they were doing. I would definitely recommend this company to anyone looking to make repairs or changes to there house.

I needed new windows for my condo as I was tired of sitting in my house feeling like the windows were open in the middle of winter. I used Diligent Exterior to replace the windows which were a variety of sizes and not "normally sized windows". I was thrilled with the work that they did and could notice a difference right away. I would recommend them to anybody that needs any window work done.
Response from the owner: Thank you for your business Mike!
