I did not decide on contracting the company for my roofing and siding projects as I found another company with the same materials used and did the job for less then this company quoted. I decided in May 2025 to go with this company for my window project that included 13 double hinged windows and 1 picture window. After signing the contract, I was informed that I would be receiving a contact over the weekend for a foreman to come out and do official window measurements for the ordering of the windows. I was called on Wednesday of the following week by a gentleman only to say " I am 20 minutes out from you." I didnt understand how he decided to just impose and not make contact prior to set up an appointment as I was told was to happen. This was the beginning of red flags. However, we made it work out as I work and was not available for this impromptu measuring. On June 12, 2025 I was phoned to alert of my windows were coming in and to set up installation appointment. I settled for June 16, 2025 starting at 8am, if weather permits. I took off of work and had all window blinds/ covering down and furniture moved 2 ft away from windows as instructed; this was a lot of work. On 6/16/25 at approximately 945ish am I received a call from a female whom informed me that the installation had to be cancelled for the date as its raining. My issue with this situation was that the company (humans) knew that it was going to rain in the beginning couple hours of the morning and could have cancelled over the weekend to be considerate of my time and not have me sitting around the house using leave from work unnecessarily; the weather forecast is online. In addition, I had to get the window coverings put back up for security and privacy. The installation occurred on 6/24/25. The company had a crew that came out whom seemed okay. I had to request that they use foot coverings; this should be a requirement and something I did not need to ask. They started upstairs in the bedrooms. They placed covering on the beds. However while working they placed tools and water bottles on my wood furniture, which was a NO NO. I didnt understand the lack of respect for my property. The crew removed old windows that were put in when the house was built 30 years ago. As they installed I noticed the windows had about a 2-3 in gap all around. That was quite alarming if the windows were measured correctly. They sprayed foam as I was explained in the gaps but NEVER pur window flashing up as I was told they would. They put caulk up only. The caulking was very messing and large amounts on my newly replaced siding. Thet also cracked the siding on the rear by the light fixture. By using the ladder and thumping it harshly up against the house; assuming it was too heavy for onw person to move creating the behavior. With that created divets in my composite front bump out with ladder prints from the cross bar type thing attached to the ladder on multiple areas. Also they didnt clean up their mess. I called after they finishes to alert of issues. It took me a couple times and then I got one of the workers that came out. Then the owner. I was not too pleased with the owner as he rushed and overspoke me as ig I dont know what to look for and wasnt very pleasant and condescending. After speaking with the owner he came out tje following Monday. And later that afternoon it rained and water poured from the front bumpout kitchen window. I called owner back on facetime so he could see the activity. The owner came out the nexr day with the crew. He walked around and said the wimdow job looks nice but never addressed my window flashing issue. However the leaking window was due to the seals around the composite bump out beinh pushed and detached; consistent with the ladder pressing on it as stated prior. The crew damaged the window metal frame and caulked it in the living room. It was never corrected or fixed. It was brought to the owners attention as well. The crew resealed the areas. The messy caulk on the back and siding, the crew actually cleaned it up the day of the window installation. The crew left dirty hand prints on my white bedroom dresser and on the walls bear bedroom front window. The crew cut out areas of my window ledge and caulked over it and it was never correctes after bringing it to owners attention. Also all stickers and hand prints were left on windows. This should have been cleaned up. The crew did not clean up their mess as I was promised. Because of my experience with the seemingly condescending attitude and over and quick talking I will not be able to give a rating higher then a 3.

I hired Liberty Windows & Siding for a large exterior renovation project that included siding,…read morewindows, doors, gutters, and a portico. I selected Liberty largely based on representations that the work would be performed by in-house crews rather than subcontractors, and that quality workmanship was a priority. Unfortunately, the project did not meet those expectations. The initial installation resulted in widespread workmanship deficiencies, including improper siding installation, flashing issues, trim defects, and other items later documented by both an independent inspector and a manufacturer representative. As a result, Liberty had to remove and reinstall significant portions of the work. While Liberty ultimately undertook remediation, the process was prolonged, difficult to manage, and required extensive homeowner oversight. Remediation details were not consistently documented in writing, work was at times scheduled or attempted without prior coordination, and key quality-control steps, such as clear verification milestones and final walkthrough procedures, had to be repeatedly requested. Even after remediation, there were disputes regarding scope reductions, credits, and whether the project could be considered complete without a formal walkthrough and customer acceptance. I incurred additional out-of-pocket costs for independent inspections, legal consultation, and missed work time in order to reach an acceptable outcome. In fairness, Liberty did return to address issues and did not walk away from the project. However, the overall experience fell far short of what I would expect for a premium-priced renovation. Homeowners considering Liberty should be prepared to document everything carefully, confirm who will perform the work, and ensure that all remediation and close-out terms are clearly defined in writing before proceeding.

The team took the time to ensure that every window and door fit perfectly, operated flawlessly, and met our expectations.

Not only were they efficient and on time, but they left our home clean and tidy at the end of each day.

None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why.

After that, communication was wonderful as were were assessed of the stage we were in.

For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.

RESPONSIVENESS - very fast, very responsive, very professional. A tad too frequent, but apparently roof repair is a competitive business. INSPECTION - scheduled and conducted efficiently; exceptionally thorough inspection report (David). COST - in line with all other quotes, which are apparently driven by the insurance estimate. Green Oak differentiation included owner interaction, master roofer certification, 5 star rating, excellent warranty, professional documentation and workflow management. WORK - scheduled efficiently, material arrived on time the day before, crew arrived on time the day of, work was conscientious and completed in 3/4 day (townhome), clean-up (including loose nail hunt) was impressively thorough. AFTER - received certificate of completion in a timely manner, along with photo record of repaired roof. Not being a roofer, it's difficult to assess the integrity of the new roof & shingles, however the end result appears clean and professional.

The free estimate happened within a few days and ended up being lower than the insurance-assessed quote. He recommended a roof "tune up" as part of the package without pushing or trying to upsell me for more, which i really appreciated. He also accommodated my inquiry of adding on the installation of a bathroom exhaust vent cap, which was missing when we moved in. After being extremely reasonable on pricing and lighting-fast on responses, they scheduled and completed the work the day after signing.
