"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."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

"I had such a great team working on my home. Every project was completed exactly how I requested and done timely. The most important factor for me was how they cleaned up after themselves after every job. Also, the constant communication. The work is definitely quality. I did everything in phases just to get a feel of their work. I had electrical and painting done in my office and mudroom. I later decided to hire them to complete some electrical, painting, gym, and storage built out in my basement. I am saving up for the full bathroom I want done in my basement. Will definitely hire them again."

We specialize but are not limited to full bathroom and kitchen remodeling. We are an all in house company pricing ourselves on knocking out the middle men (subcontractors). We believe that the quality and customer service is better when the work it started and completed by the same crew through the entire project. We offer many other services including flooring, painting and more. All the way down to finishing basements. See what we can do for you.

"Converted a loft into a room. We went with Bradford Renovations and couldn't be happier with the results. In just two days, they completed the project. They did significant prep to keep drywall dust contained. Results turned out great."

"LFC Services and Home Repair was Great! My wife and I were looking to have specific work done on our brand new home that we didn't have our builder do when the house was being built. I contacted Tony Heard of LFC to come give us estimates on the things we wanted done. Mr. Heard was prompt, very courteous and respectful. Mr. Heard was very attentive and understanding of our requests. After the initial conversation with Mr. Heard we were excited to allow his team to complete the tasks.

"2 of 997 Urgent: Project Management Issues & Pending Renovation Work We are experiencing significant project management issues that have caused unnecessary delays and frustration.Their quality of work is good but project management sucks big time,. We started our bathroom rennovations on Nov 29th 2024 the project wsda supposed to be completed in 5 weeks now it is almost 2 months and the master bathroom still needs to begin constreuction. We have had 3 project managers so far. However, despite multiple follow-ups over the past week via our text messaging group and several calls, we have yet to receive any updates on a variety of outstanding work in the loft and guest bathroom that need to be done. This lack of communication and progress is unacceptable. While we understand that Elkay is taking a break, the responsibility for keeping us informed and ensuring the project stays on track should not be neglected. We are not getting proper updates about stataus of several pending issues and we feel like we are being passed around without any clear resolution or accountability. The most pressing concern is the arrival of the bathtub, as all further work on the master bathroom is stalled until it arrives."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
