Standard Water Control Systems is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

"Before you hire any Water Control company hire a plumber to make sure you really need drain tile. After we hired this company we still had seeping water issues. After they were called twice they finally told us we had a leaking pipe. In addition, an employee stole a cellphone and a FITBIT watch from our home and damaged our egress window. They fixed the egress window. The owner was not very pleasant, made us feel like we were not telling the truth. My husband literally spent hours changing passwords and canceling credit cards since the cellphone contained sensitive information. A few days later through Google find my device we pinned the cellphone at this business location, we called the police and had to take time away from our work to retrieve our phone. We never retreived our FITBIT watch. It was a nightmare! The company apologized but the damage was done!! The job itself was OK.. Apologies are not good enough after the hell we went through!! Watch who enters your property!! "

"The project eventually got finished. Might have been a little more complicated to get started on as it required the city and contractor to communicate seeing as it was a city renovation program. Things I?d like to go better is cleanup and mitigation of dust. It was limited to whatever steps I took. The pump has to be reset 1 to 2!times through a span of 60 days or so. Not sure if that?s normal and to be honest I haven?t yet reached out or looked into this on my side. Aside from that Mr Brown was easy to talk to and respectful as was his workers. When the work finally started to was down quickly. There were parts that could have gone better but it could have gone worse. I won?t say I wouldn?t recommend them at the same time I think there?s something?s that could definitely improve upon. And to add it did pass City of Plymouth inspection and their requirements for the program. I?ll have a better idea of how this works out in the future."

"This company is amazing. I would highly recommend them for anyone seeking to evaluate their own home or to look into future home purchases. I have a 100 year old home with several challenging drainage areas, that are hard to address. I really appreciate the way they thought through the problem holisitically and helped me to come up with a a reasonable plan. They also helped me to avoid some advice by a Basement Repair firm that would have not been helpful."

"I appreciated the accurate estimate for the work as well as the advice on preventing it from happening again. The crew arrived on time and raised the walkway section so it’s level now. They also caulked between the driveway and garage slabs."

Minnesota's Window and Siding Installers since 1981. Free Estimates, No pressure sales, and Great Savings on Vinyl Windows, Siding, and Doors. Our other specialties include building custom homes, additions, four season porches, outdoor kitchens, gymnasiums. You dream it we have the skill and experience to build it. Additional email - [email protected].

"Sandau Construction recently completed a window replacement project at my home. They were one of five contractors that I had out to evaluate my project and bid the job. The sales presentation was low pressure, comfortable and offered adequate time for question and answer. The company’s subsequent follow-up to the various questions and issues that I had was prompt, direct and informative. They never tried to “sell” me anything and focused solely on my desires and priorities. Their overall project pricing was competitive overall, versus the other contractors who visited. Pricing was clear and upfront and included no promotional games or gimmicks. With any major home improvement, one doesn’t want to overpay just to ensure quality. The Sandau Price to Quality dynamic was right where it needed to be. Given the high home improvement demand that has been experienced during the pandemic, along with supply chain issues, there was a very lengthy delay from the project down payment to the actual commencement of the job. Once underway, the project installation proceeded quickly. Installers were skilled, agreeable and proceeded in an efficient manner. The final results exceeded expectations. As window replacement is a major investment and expense for any homeowner, getting that all important comfort level from the contractor you’ve chosen is critical. I felt good with my initial selection and was also rewarded at the project’s conclusion. I highly recommend the company to anyone who is interested in a high quality experience in sales, service and product offering. Thanks both to Graham in Sales and to Stephen my Project Manager. Well done."

Basement Waterproofing questions, answered by experts

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Ductwork sweats for the same reason you might find beading on your windows or why cold drinks drip in the heat—temperature difference. When you see your ductwork and you notice sweating, that's a sure sign that your system is not operating anywhere close to peak efficiency. The best way to keep ductwork from sweating is to wrap it in inadequate insulation.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
