"Weaver did very well with our basement finishing. They did get the way we wanted things done, which was a bit unique, but they did miss a few things, like not understand we were going to take care of some things that were non-standard ourselves (because they were non-standard.). They also did leave us hanging a little at the end - we still never got our light switch at the end of the stairs hooked back up to the light, nor found out how to change the cam lights, but at some point I just gave up, cause they were kinda done with us after they got their last payment. Generally good to work with, they did have a bit of a time getting workers due to COVID, and there were some small less than desirable messes left. But thatâ  s small compared to the overall work, which was good. So Iâ  m pretty happy overall."

Norse Construction, LLC is a unique small business. Over my 30 plus years of construction I've had numerous customers tell me of contractors who don't show up, don't clean up after themselves, build what THEY want and NOT what the homeower wants. Its simple. I started Norse simply because you should have what YOU want and when you want it - period.

"We attempted to have our unfinished basement finished in 2020. The project started in June of 2020 and was terminated unfinished in January of 2021. Total cost of the partial project was $75,771. Several issues led to the termination of the project. The primary was lack of actual project management and ability to take responsibility for errors by the contractor, which, in addition to being frustrating, contributed to the unnecessarily long project time of 7 months while still not being finished. Examples include: - An I-Beam for a heavy-bag track was to be installed on the ceiling. It was installed in the incorrect location and extremely poorly, to the point where flanges were overlapping. When confronted, the contractor stated that it just "wasn't finished". However, the correction required the complete removal and re-installation. Then the contractor claimed the issue was due to insufficient instruction supplied, even though all required information was in fact supplied. The installation crew was simply not competent and failed to install as instructed. - Wood panels were put on a large portion of the ceiling. Several conversations in writing instructed that there was to be no more work done after the initial paint as we liked the look as is. When painters were on-site for the walls, it was confirmed with them verbally that the ceiling was complete and not to perform work on them. However, they caulked and painted it anyway. When confronted, the contractor stated it was always known that this work was to be done. He also said it was only painted and not caulked, which was clearly not the case. Additionally, when shown texts and emails where we explicitly requested no more work done to the ceiling and that he also stated it was complete, he simply ignored it. - When ordering a vanity, he sent us to a shop to select one. However, when it came time to need the vanity, we found it had never actually been ordered. The contractor blamed us for not ordering it while at the shop, however the person at the shop later confirmed the hold up was the contractor not confirming the order. These are some of the biggest examples, but there were communication issues throughout the project. The termination of the contact didn't go any better than the rest of the project. We were told up front, in writing, that we would be billed for all services each week for the prior week. However, when we were settling up after the contract was terminated, there were many costs he was back charging for, meaning they were not billed during the week of work as the original contract stated. One of the items had no reciept. One of the bigger issues here was the painting. The painting cost was much too high relative to the original bid price based on actual work performed. When asked for an itemized bill for painting, it included painting work that had not been performed. The contractor ultimately removed the item for which he didn't have a receipt and reduced the paint cost by some amount. It was still not correct, but we agreed to pay to end the situation."

FAQs for addition to existing structure building service projects in Florissant, MO

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
