Double Helix Construction LLC

I highly recommend I was worried about finding the right contractor to replace my aging roof. I called several contractors and they all seemed scared of the complexities of my roof with several hips, valleys and steep pitch. I sure am glad I found Double Helix. Dwayne was professional and his crew did awesome work at a great price. They showed up on time, protected all my landscaping and cleaned up 100%. All my neighbors are jealous of my beautiful new roof .

Dwayne and his team did an amazing job on our new roof! Communication and execution is their top priority. Hire these guys and thank me later!!!

Would give a 10 star rating if possible! From estimate to clean up, every part of our roof replacement was a breeze with Double Helix!

I used Double Helix for siding and gutters on my 1978 home.
Dwayne is a top notch professional! He was not the typical pushy salesman like some of those other companies. He told us straight what he could do and delivered exactly what we agreed on. The quality of the work is superb. Fair prices and Great customer service are what you get with Double Helix. I definatley recommend.

We are very pleased with the work completed by Double Helix Construction. Our home improvement project included 28 windows and 1 exterior door. Dwayne and Cynthia communicated with us through the entire project. Tim and Joyce were professional, punctual and experienced installers. We appreciate Tim reaching out to us before install date to keep us up to date on the project. Great experience overall. We look forward to future projects with Double Helix Construction.

There was full communication from start to finish of this project. Tim and Joyce worked very well together - Joyce had materials and such in place prior to Tim it. Joyce did a fantastic job cleaning the glass after installation.

I purchased an inner door leading from the garage to the house. It was custom made to my specifications. Dwayne is so helpful in showing different options and he answers every question. The installation was great, quality workmanship, cleaned up everything. Will definitely be using Double Helix again!

We couldn't be happier with our new ProVia entry doors, or the service we received from everyone at Double Helix! Dwayne, Tim, Joyce, Cynthia, all at the top of their game. When you buy the best, you only have to cry once!

Double Helix is all the things other construction companies and handymen are not. They return phone calls. they come out and give you an estimate. When they say work will start, it starts, when they say they will be finished, they are finished. Start to finish, initial message on facebook to completed job, two weeks and one day. And that included two holidays!! and they threw in a couple of extras to improve the looks of the house for free. Call them!! you will not be disappointed!!! 5 STARS+++!!

We needed new windows. Got 2 estimates. Double Helix not only had the BEST price and also presentation, but a great product!
We are so happy with the product, the owner, Dwayne knows his stuff. AND, not to forget Tim and Joyce on the install side. Just an amazing experience!!! Would highly recommend!!

Double Helix did an excellent job replacing our exterior door. When Dwayne came out for the estimate he showed us all of our options and helped us find one to fit our budget. It took no time at all for our custom door to be made. When the time came for the install, the team worked with our schedule, were courteous, cleaned up, and disposed of our old door. We will definitely call them back for future home improvement projects and highly recommend Double Helix Construction!

I recently had the pleasure of working with Dwayne, the owner of Double Helix Construction for the replacement of three exterior doors to our home. After conducting thorough research, I knew I wanted Provia Doors because of their high quality and added safety features. I reached out to several contractors, and after reviewing their quotes and options, Dwayne provided the most affordable solution.

The installation process was coordinated seamlessly by Tim. Upon arrival, Tim, Joyce, and Danny, quickly got to work removing the old doors. Upon removal, they took care to address pre-existing water damage around two of the doors, which they promptly addressed by replacing the damaged materials. I sincerely appreciated their attention to detail and commitment to doing the job right, even when the scope expanded due to prior water damage.

Throughout the entire project, the team was professional, communicative, and efficient. They not only completed the installation of Doors on time but went above and beyond to ensure everything was properly sealed and functional. Their work was clean, thorough, and the results are fantastic.

If you're looking for reliable, professional, and affordable service, I highly recommend Dwayne and his team at Double Helix Construction. Thank you again for a job well done!

I would use Double Helix again. The communication through out the entire process of replacing our roof was consistent, timely and very professional. The teams that did the actual work were very talented. The roof on my home had several areas that needed special attention in the finish process. It was done perfectly. Thanks for a job well done.

Absolutely happy. We needed a new backdoor and found DHC at the Fredericksburg home show. They came out quick, help as we made a selection and placed the order. The install team was great. They were quick friendly and professional.
Will definitely use these guys again.

Dwayne and his team was awesome! I had 14 windows replaced and the change in room temperature has been MAJOR. The crew replacing them were very thorough and and did an amazing job. The caulking they used had a strong odor but after three days it was gone, which was also the amount of days we had to give the caulking to cure. They used Provia windows which come with an amazing warranty. Thoroughly impressed with Double Helix and will definitely be recommending them.

Thank you so much. I called they came out next day for estimate. I had a shed roof replaced that was in bad need of new roof. I'm so grateful. Got roof done in a day. It looks beautiful. They cleaned up after them selves. You'd never know they were here. Except looking at new roof. Scheduling of getting roof done was pretty quick. I record them highly. I believe it's above and beyond service. Thank you so very much

Company responded promptly to my call and followed up promptly throughout the process of installing sliding glass doors. I was informed a week before installation that we were on schedule and a definite date would be set soon. Workers were knowledgeable and efficient, cleaned the area inside and out, and left me with a beautifully installed door with shiny clean glass...top to bottom.
They instructed me about the locks, etc., and the owner called next day to see if everything is meeting my expectations.
I highly recommend this company for pricing, workmanship, quality materials, and follow-up. They truly care about their work.

Double Helix did an excellent job of installing my seamless gutters. They even installed them on a day it was raining lightly which allowed me to watch them draining properly as they were installed. Dwayne (the owner) called to let me know when they were coming and when they did not arrive at the time he called to update me with a new arrival time. The installers were professional, polite, worked quickly, and cleaned up after installation. There was one issue after installation. A hidden hinge screw broke off and when I called Dwayne he had the crew return and replace it the same day. I would definitely recommend double Helix to anyone who wants professionally installed seamless gutters

These guys made door buying so easy. Thank you for taking the stress away. From beginning to end it was a smooth transition. Our installers were so courteous, clean,vand organized too. Great experience all around.

Absolutely love the work done on our roof. They got it all done in a day and then gutters done right after that. Dwayne was a pleasure to work with. Thank you for your work!!

If you're looking to get your roofing and gutters replaced, look no further. Double Helix just finished an outstanding service for both on our home and we are wishing we had done this years ago! It's makes our home look so beautiful. Their caring and knowledgeable Team made the process from sales presentation to completion easy and pleasant. So give them a call and see what they can do for your home today!

Excellent work. I would recommend this company to anyone. Workers were efficient and attentive to detail. Cleanup was outstanding. Finished product was exactly what I expected. Costumer service was outstanding

We needed a new door, our old door and frame weren't straight at all, the work on the door is beautiful, and the job was done in a professional and timely manner, friendly people too. Would recommend and will reach out for future house upgrades.

I'm very happy with my new front door and storm door. I worked with Dwayne to customize, and it was ready for installation sooner than expected. Tim and Joyce spent the entire morning installing the doors and ensuring everything was just right. They left the entryway cleaner than it was before they arrived. Thank you, Double Helix.

Everyone was friendly and courteous. Made sure everything was cleaned up before they left. Were on time and the job was completed that day!

Double Helix did what they said they would. I was given a time frame for arrival of 3 doors, and they showed up with time to spare. Installation was scheduled for a Thursday, installer did have to push by a day due to unforeseen circumstances. Installers arrived on Friday within their time frame and had all 3 doors installed and cleaned up within roughly 4 hours. I will be having Double Helix come out and install an additional door in the near future. Wonderful experience!!!

We had windows, gutters and
downspouts replaced by this

very quick. Even greater news..

perfect scenario for any of your
outside home refurbishing needs!
DOUBLE HELIX will be returning
to replace our siding. We can't
wait!!!

These guys did a fantastic job for our roof replacement. The roof installed and all cleanup done in one day and then the gutters were done in less than a day afterwards. Great quality work. Would recommend highly!

Very friendly, very professional people. I had some windows and a door replaced. They had everything done in no time and the room looks great.

We had windows replaced in our home. It was by far the smoothest process my wife and I have ever experienced. From the initial discussion of the details of the job through the actual installation, everything was handled in a total professional manner. The team, from sales to installation, were first-rate. I highly recommend this organization.

New roof - areal pictures taken by Angusto's drone - fast and efficient - 6 very hard working men - and they seem to be having lots of fun after a long day work during clean up. Plus 1 supervisor - 2 delivery men - 1 company owner. 35 shingle bundle, 9 facets, 5/12 grade, ridge vent added - 40+year roof didn't require them from before - hope this one last as long.

I purchased a new front door for my home in April 2023. I could not speak more highly on how good the communication was to me from the employees at Double Helix. I was receiving phone calls to let me know the status of my custom made door as well as scheduling prospects. Once the door arrived and was installed, the team did an AMAZING job taking my old door out, removing old molding and replacing it with new molding, new insulation, making sure my door lined up perfectly and was sealed properly. They also cleaned up after themselves prior to leaving. 10 out of 10 would definitely recommend Double Helix to others !!

The installers were excellent! They were very thorough with cleaning up and removing the old windows. And they had all 18 windows and sliding glass door installed in one day! Five stars!⭐️⭐️⭐️⭐️⭐️

They did a wonderful job on my roof. My new shingles look good, and my roof looks so much nicer. They didn't waste any time getting the work done either. I totally recommend them! They cleaned up nicely after the work was done and left no trace of them having been there, other than a great looking roof!
