We recently had a positive experience with Wellmade when they installed their "Sunset" model shed unit in our backyard, and we are very satisfied with the outcome. From start to finish, the process was seamless and efficient. The project was completed without any delays or interruptions. The team of builders and contractors were highly professional, respectful of our space, ensuring minimal disruption to our daily routine. Communication with Wellmade team was clear and consistent throughout the entire project, which we greatly appreciated. Overall, we highly recommend Wellmade for their excellent service, professionalism, and the high-quality shed units they provide.
I recently had the pleasure of working with Wellmade to create my dream outdoor studio shed, and I couldn't be happier with the result! I went with their Presidio model, and from start to finish, the team at Wellmade was professional, attentive, and incredibly skilled. They listened carefully to my ideas and preferences, making the decision making process very easy, and their expertise in design and construction truly shone through in the final product. The entire process was smooth (the crew was very kind, tidy and kept to themselves) and stress-free thanks to their communication and attention to detail. I highly recommend Wellmade to anyone looking to enhance their outdoor space with a custom-built structure. I would definitely use them again if we need another structure built down the line. Thank you, Wellmade, for bringing my studio to life!
We had a wonderful experience working with Wellmade. We went with the Presidio model to be used as a two person office and while we were initially concerned that it might feel tight for two workspaces it turned out to be quite comfortable. The project came out great and just as we had imagined. It looks exactly like it did in the pictures. We are also glad we went with some of the extra features like the heated floor and skylight. One of the big benefits of working with Wellmade is that as advertised you really don’t have to manage anything yourself which was a big relief for us after having mixed experience trying to manage work with other companies for past home projects. Our office replaced an old metal toolshed that had to be removed first and we were debating whether to try and remove it ourselves or ask their crew to remove it and I’m relieved we had them do it because it turned out to be quite an involved process but their crew did it very efficiently and it only took them half a day. Even with the extra task it only took them about a week to complete the project. The building crew was great. They were super nice, hard working, and did really good work. They showed up early, stayed late every day, and worked through the rain. It was fun to watch the very quick building process. Despite the speed of building they never seemed rushed, working to get the details right before they moved on to the next step. Finally, we had some bad luck with the timing of heavy rain coming soon after they finished which messed up some of the paint on the trim that hadn’t totally dried yet but when we reached out to explain the issue they were great about coming back to fix it and being sure to let us know they would come back again if the issue returned. In the end everything turned out great and we’re very happy we went with Wellmade. Down the road if we were ever to add an ADU we would definitely work with them again.
We had a positive experience with Wellmade and are really appreciating the Presidio shed they installed in our backyard. It is working well as an office space for us and has made our home overall much more comfortable and functional for our needs. Like many people here, we were searching for a bit more space to accommodate additional work-from-home and a new family member, and landed on Wellmade because we wanted to use a local company and didn't want to have to hire a crane to make the project work. Wellmade met our timeline, getting the shed installed during the one stretch of good weather in February of 2023, a few months in advance of baby's arrival. Communication with Kirill and the general contractor on the project, Tyler, was good. Both of them were very nice and accommodating and maintained good humor throughout the process. Kirill had to make custom modifications to the design of the shed to help us get permits, which is required in our city but not in most places they work. This got in the way a bit of their one-week construction goal, but the team worked very hard to keep things moving quickly despite having to wait for inspectors on certain days. The shed looks very nice and guests always have a positive reaction to it. It is a delight to work in with great light and a comfortable temperature regardless of the weather, thanks to the heat pump. We are happy that Kirill convinced us to put it where we did in our yard. There were a few issues with finishes that Kirill had to send team members back to fix, but he addressed these without any pestering on our part. 8 months in, we are very pleased to have this extra space in a good-looking and comfortable building, and have recommended Wellmade to friends and neighbors looking for a similar product.
We are extremely happy with the Sunset shed and would definitely recommend Wellmade. The process went very smoothly. Our shed was finished in 6 business days. We were amazed at the quick progress each day. The crew started early and worked full days. They were very nice and communicated really well throughout the process. The shed is high quality and my wife and I are looking forward to working from home. It's nice to get a well designed product from a local Bay Area company.
