A Dream Realized: Unreserved Thanks to Coastline Sunrooms & Awnings! Working with Adam, Dan and Greg at Coastline Sunrooms & Awnings on our new Temo sunroom was an overwhelmingly positive experience, and we are absolutely thrilled with the finished result. This review is less about the steps and more about the dedication and heart this team put into making our vision a reality. From the start, we presented Cosstline Sunrooms & Awnings with a challenging situation: a clear, non-negotiable vision for our dream sunroom that frankly exceeded what our initial budget could comfortably support. Most contractors would have simply told us "no" or scaled back the project drastically. Instead, their team treated our budget as a puzzle to solve. Their commitment to delivering exactly the Temo room we wanted—not a compromise, but the authentic space—was phenomenal. They worked diligently, utilizing their expertise to source materials and plan phases in a way that maximized every dollar, ensuring we got the luxurious, four-season room we thought was out of reach. Was the process 100% smooth? No major construction job ever is, and there were the inevitable small delays and coordination challenges that come with any complex build. But what sets Coastline apart is their unwavering dedication to the final outcome. The team never once wavered in their mission to deliver our specific, ambitious design. The craftsmanship is impeccable, the Temo glass system is flawless, and the room has immediately become the heart of our home. It is a stunning, high-quality structure that adds tremendous value and joy to our daily lives. We recommend Coastline Sunrooms & Awnings with the highest enthusiasm, especially if you have a demanding vision or a complex budget to manage. They didn't just build a sunroom; they delivered a commitment, and for that, we are eternally grateful.Posted on April MitchellTrustindex verifies that the original source of the review is Google. It's so nice to work with a crew that is nice, polite, and courteous from start to finish. Susan started the experience off great with a brief company overview and really set the tone for the rest of my experience. Look forward to seeing what else I can come up with for my outdoor living space to have Dan and the crew come back out!Posted on Robert RandallTrustindex verifies that the original source of the review is Google. Adam at Coastline is one of the BEST new authorized TEMO DEALERS we have added in many year. The homeowners in Delaware will be satisfied with their service, products and communication to complete their projects. You are in good hands!Posted on Victoria FayaTrustindex verifies that the original source of the review is Google. I don't ever leave bad reviews for anyone or any company but I do need to share my experience with Coastline. I chose them because I had read some positive reviews so when I wanted to have an awning or shade done over the door out of my sunroom, I gave them a call. The gentleman that came out to the house was nice, respectful, professional. He was knowledgeable regarding the different available products. Was here for quite a while. Gave us some different ideas. Took measurements. Assured us we would have a quote by that evening. We didn't get it. Waited through the weekend and Monday still no quote. Tuesday I called them to make sure they had the correct email. They told me they were having server issues and would send me the quote soon. Another week has passed and nothing. No quote, no phone call. I totally understand if they didn't want to take the job because it was too small for them. As professionals, they should have just called me and told me. Disappointing!! I wasted time waiting for their quote while I could have been looking elsewhere.Posted on Rebecca SnyderTrustindex verifies that the original source of the review is Google. Extremely pleased with my screened in porch. It looks so nice! Customer service was excellent.
