DNR CONSTRUCTION INC

Initial call and owner, he didn't try to sell me anything else he made an immediate arrangement to come out the next day. Gave a price that was fairer than competitors. Vedel, Leo, George, Alfonso, and Cesar they were professional, courteous, competent ,left my property clean and tidy. They were knowledgeable and expedient . I highly recommend them.

The team arrived promptly. One man set up the blower door test equipment and measured air leaks while the other man walked through the house with me checking walls and ceiling temperatures. The entire process took less than an hour. They concluded that my house was as air-tight as it needed to be. I exchanged a few Emails with them in the following days to discuss sealing the gaps in the attic. They discouraged me from doing so because they felt that the house shouldn't get any tighter. I was very pleased with their service and their willingness to engage in an email conversation afterwards. I would use them again.

Crew arrived on time, worked quickly and kept everything clean. I was able to view the work every step of the way. Good job.

The contractor was honest and said that given our lack of attic space, there would be no place to put the attic insulation and no point to run the test, since he wouldn't be able to help us save on energy costs, since there is nothing he could do. He was generous with his advice on how to save energy in a few places which I found problematic. I found this company refreshingly honest, as far as contractors go. I would definitely recommend. He gave me great free advice. If we need windows or doors replaced, we will definitely use DNR construction.

Overall went well. Insulation work was well done and definitely improved comfort in the home. Was not impressed with finishing however. They were forced to take up some wood flooring in one area and did a poor job of replacing it. As part of the job they also had to cut several holes in the drywall. They cut all the way to the baseboard making the repair much more difficult without removing the baseboard. The crew was thinking finish quickly not necessarily the work I would be doing to clean up afterwards. I would not hire them for finishes but they did a good job on the insulation.

I chose DNR to insulate our attic because they are on the list of approved contractors for the Peoples Gas Home Energy Rebate program. I should note that in order to qualify for any rebates through this program, you must first get an energy audit done, which will cost $99. After getting the audit done, I was able to get an estimate for the attic insulation, which came out to $2500 but would be $1800 after rebates. The estimate seemed a little high, but I had already paid for the audit with DNR and didn't want to do it again with a different company, so I went with it. Tom (the owner) was also very nice and communicative about what kind of work needed to be done. As a woman I always appreciate not being talked down to about jobs like this. DNR also deals with all the paperwork for the rebates so you don't have to bother with any of it or wait for the state to process anything. It took a few weeks to get an appointment scheduled; I had to call a couple of times to follow up. I assume this is a busy time of year for this kind of work. When the guys came to do it, they were in and out pretty quickly (all told it took maybe 6 hours?) and I did not have to leave the house. They laid out tarps to try to keep from getting my floors messy, which I appreciated! On the other hand, they also moved furniture without moving it back and put a bunch of either foam or caulk canisters to soak in my bathtub without asking me, leaving a pretty gross ring around it for me to scrub. There were also lots of small nails left on the floor near a door that was weather-stripped. Glad I wear shoes to go to my basement or this could have been a nasty surprise. All told, I'm glad I got the insulation done and I hope to see a difference in my gas bill next month. The house does feel less drafty, though I couldn't really say it feels warmer because we've had such extremely low temperatures in the week since the work was done. I wish that the workers had cleaned up after themselves better, but it wasn't anything I couldn't handle.

Improvement of about 30% of cold air coming into the house. very professional, cleaned up after themselves.

The air sealing was great. The house is much less drafty, making it feel noticeably warmer at the same temperatures. The insulation seems to have been done well. On top of that, there was an issue with our 2-year old boiler that really seems to have been coincidental. DNR had had to turn the thermostats down to run the blower door test to show air-leakage improvement. When we turned the thermostat back up, we didn't initially notice that the boiler hadn't come back on. That evening, several hours later, with the house at about 60 and a predicted low in the single digits, we called DNR to see what might have happened. They sent Nick, the HVAC manager, out immediately. He looked things over and ultimately sanded the spark-plug (not actually a spark plug, but something similar) to clear it of carbon build-up, and that did the trick. Nothing they had done would have created a rapid carbon build-up, so it was either completely coincidental or maybe having the basement get cooler during the blower-door test had meant that a soot-covered part no longer worked. I was present for all of this (and had already done some troubleshooting myself) so I'm confident this was the issue and that it didn't have anything to do with their work. At any rate, they did this for free, which got our boiler running and our house warming up. In the course of this, we realized there was water on the floor - again unrelated to their work. We had a fuse blow a couple weeks before, and it seems to have blown the water pump necessary on a modern high-efficiency boiler. It was now nearly 10:00 pm on the Friday after Christmas. Nick rushed to Home Depot to beat their 10:00 closing, picked up a pump and installed it. Far beyond the call of duty. We really appreciated the quality work and the attention they gave us in a tough (cold) situation that turned out not to have been their fault. We will be using them again to do similar work on a 2-flat we own.

Great! I was using a state program to subsidize insulation and DNR was one of the recommended contractors. They were fast, efficient, and we could tell a difference in temperature in our house immediately. We have a flat roof, so they had to cut a hole in our 2nd floor ceiling and blow the insulation into the space. they also built a nice insulation box around our skylight. Very good! I would hire them again to do other projects.

DNR is a #1 contractor that will always get my business

An engineer came to make an estimate. He measured how mach air does my house leaks, inspected attic and crawl space. He suggested couple of options for insulating crawl space and attic and sent me an estimates with rebates from local gas and electric companies in about 4 days. A week later exactly on time a crew of for men nocked on my door. They sealed house walls and some other places, insulated crawl space walls with foam boards, put 47 inches of celluloid into attic. They put dump cloth on the floors and did not let a spot. Engineer came again to make measurements, he also took care of rebates. With rebates it were supposed to cost me $2305, with rebates he got me it was only $1280. Overall they were very professional and I would recommend them anytime. In fact I already did once.

The workmen were prompt. They insullated my flat roof cavity of the multi-unit, air sealed the basement openings, insullated under the flooring on the room addition, on a multi-unit building. The work was done in one day from about 9:00 am to 6:00 pm. The workers were diligent, respectful. I would hire DNR CONSTRUCTION for any future insullation projects.

Prompt service. An area of bricks were deteriorating and it was repaired in a day.

I got estimates that were a lot lower. At the time I didn't have the money to do all the things that needed to be done to the house.

They did very well. It hasn't leaked since they did the work. It was a small job and they arrived and did it and it worked so it was pretty good. We would use them again.

Extremely pleasant process. They took the time to answer our questions before we decided to go with them. The day of the installation they did a great job of cleaning up after the job was completed.

The DNR team was incredibly professional. They contacted me quickly with an estimate and took time to answer all of my questions.The team showed up on time and completed a high-quality job in one day. I was pleased with the quality of the work, the professionalism of the team, and the competitive price for the project. They were very helpful in identifying sources for rebates and filling out paperwork for the rebate, which significantly lowered the total cost of the project.

The crew was courteous and professional. They laid drop cloth so as not to damage my carpeted or tiled floors. They carefully removed all existing trim. removed the old windows and installed the new ones. They insulated all the gaps and replaced the interior trim. The exterior was finished beautifully. They cleaned up the job site completely and hauled away our old windows.

I had them come out and put in foam boards to reduce air flow. They say there was leaks around the windows and caulked it. They had to come back and redo the patch on a non used vent. I think they did do a good job to reduce the air flow. I went to paint the kitchen and I discovered the caulk wouldn't cover the paint. I called them and they said they used non-paintable caulk. They said that the owner said that they would not come out and redo it for me. Surely they should know that they should have used outdoor non paintable caulk inside. I had to remove the caulk and redo it myself. They don't take responsibility for the work.

I liked their services and will use the same in future.

I did this work in conjunction with the Historic Chicago Bungalow Assn who recommended DNR. Tom came out promptly and provided me with a written estimate. The work was done in a timely manner and professionally. DNR provided the necessary forms to apply for the HCBA grant as well as forms to apply to Peoples Gas for a rebate.

They were recommended to me. They were excellent. Their price was market. It was very reasonable for what they did. They were very responsive. They did exactly what they said they were going to do when they said they were going to do it. They were pleasant to work with and they cleaned up after themselves. I had a good experience with them.

I called Tom to provide an estimate for some airsealing and insulation of basement joists, attic and cantilevers. He came out promptly, was courteous and informative providing extra FYIs about how insulation works in general. After looking at my house and going over the energy audit I had had done, he said he hated to say it but he didn't really feel comfortable providing their services because it would make my house too airtight and might cause air quality issues. He went on to say that for about 3K they could perform the work but the difference in comfort would be slight and might not be worth the cost to us. I told him I appreciated his honesty and would definitely be calling their company in the future if I need any of the other services they provide. In this day and age, it's nice to come across a company (Tom is one of the owners) that is not only interested in making money but in providing quality service and he felt in our case that they couldn't make a big enough improvement and could possibly cause a problem. Kudos to DNR Construction.

Excellent. They have come out on two occasions since installation, one when I did not know how to take out the screens and another time when there was leak after a heavy storm this summer (2010). Good company.

t went extremely well as stated above.
