Together the John Krause team creates a superlative custom home building and home improvement experience tailored to the needs, wants and dreams of each client. We are passionate about our client relationships and this is reflected in all that we do. From the in-house design process, interior and exterior customization and artisanal craftsmanship to the professional management and accurate fixed pricing, our aim is your total satisfaction with your new home, architectural restoration or home remodeling project. 

"I am writing to formally express my deep dissatisfaction with the recent retaining wall replacement project completed by John Krause Construction (JKC) at my property. After reading positive reviews and receiving an estimate that, although over my budget, seemed reasonable for the work involved, I made the decision to hire JKC. Unfortunately, this has proven to be a significant mistake, and I am left extremely disappointed with both the quality of work and the overall experience. Here are the main issues I encountered: 1. Unprofessional Behavior: The crew exhibited unacceptable behavior while working on my property. Not only did I witness them disposing of bodily fluids on-site, but they were also disrespectful and dismissive. when I raised concerns no response was received. I now smell urine when entering and exiting my garage. 2. Unresponsive Ownership: I have attempted to reach out to the owner multiple times to address these concerns and resolve the issues, but my messages have been met with silence. This lack of communication is incredibly frustrating and has only added to my disappointment. The owner refused to speak on the phone since the owner was made aware of the call being recorded. 3. Property Damage: During the construction process, my property was left damaged in multiple areas. This included e.g., landscaping destruction, equipment damage. Personal crew members vehicles being driven through my yard leaving deep tire marks damage. 4. Subpar Quality of Work: Despite the high cost of the project, the final result does not meet the standards outlined in the estimate or contract. No proper grading was completed. Every time it rains pools of water sits in front and behind the wall. The response received was. “we have passed all inspections.  There will be some water pooling while it is settling still. Plus the fact of the hard rain today, it will happen.” The wall has been completed for 2 months. Given the extensive problems, stress and anxiety I have faced. I do not recommend John Krause Construction."

The North Star Companies, LLC, is the premier contracting company in MD. We pride ourselves on delivering a quality service, at an affordable price, with the customer's best interests at heart.

"We have used The North Star Companies for several jobs in the past, with the most recent being the largest. We hired them do a complete renovation of our home in Severn. The job grew larger as demo began and turned into a job requiring the rebuild of exterior walls, demo of concrete slabs - basically the house had to be rebuilt from the ground up. All new plumbing, electric, framing, windows, siding, roof, etc. I have known Chris for 20+ years and was confident that our forever home would be solid and done right. We had a few hiccups throughout the process - as this was done during Covid, so there were supply issues, delays and so forth, but Chris and his guys did an amazing job. We couldn't be happier and are continuously getting compliments on our beautiful home. Chris has been and will continue to be our go-to for any construction needs for us and our family and friends."

FAQs for addition to existing structure building service projects in Waldorf, MD

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
