K & K Construction

Great experience using K&K. Would use again.

great 👍, perfect

Very well - efficient & high quality work

It went without a hitch, and I felt treated very well by them. And I highly recommend them to anybody, They were honest, and they did exactly what they were going to do.

The project went really smooth and met all expectations.

Very impressive work -- hard workers -- arrived on time -- top quality work. We would highly recommend K & K Construction.

Excellent! K & K did exactly what they said they would and more!

K& K did a great job for us. They completed more the 6 different jobs, and all were done very well.

They've been terrific. They were able to give us good suggestions, the work has been excellent. They show up on time and they are very responsive.

Concrete was a wrong color cracking out now have ask several times to come out no-show! I don’t think they cared they get their money! Never hire again!

Our stamped concrete sidewalk cracked in three places. I have emailed numerous times and I can not get them back out to the house to take care of these cracks. They came out one time last year but never followed up to fix the cracks. I am ready to file a report with BBB. The cracks happened right after they poured the sidewalk. I have a friend who has the same problem with them difference service. I will not recommend this company unless they show some customer service and fix the cracks plus the way they finished the sides of the sidewalk was very sloppy. I don't think I am being unreasonable. Pictures are attached.

They seemed to be very attentive to any of the concerns I have. I think they were kind of pushed by schedule quite a bit, so the first day they came in and they tore out the garage floor and they put in one sidewalk. So, in one day they tore the garage floor and poured the sidewalk. That evening we had a hailstorm and immediately called them, they showed up the next morning. They said that they can patch it up but I wasn’t too sure about that. They wound up tearing it all out. Then they moved on to the driveway, but they were still trying to make their two-day schedule and my impression was they got a little bit behind. The concrete was coming and their guys were scrambling like crazy to get the driveway in. So, I’m not a 100% confident that they got all the reinforcement in correctly, et cetera, but I didn’t get to see it, so. I inspected the forms and it was all fine, but I didn’t see the reinforcement. Their pricing was a little bit than the others. They knew what they were doing as far as concrete work.

Installation was quickly scheduled. There was a last minute reschedule due to rain on the scheduled installation day. Demo, form and pour were done in a single day. Second day was cleanup and sealing the stampped concrete. Their bid was accurate. I expected to have to fix some of the landscaping since the drive size was increased by 2 feet. I have some cleanup to do. They were accommodating for changes while the project was underway. You should be present for a project this size as there is always things that come up. There are a few minor details that could have been done a little better. Some of the joint lines are not perfectly straight and even. Some of the brush finish isn't even and has a different texture/color. This comes from brushing different sections at different points during the curing process.

Don't do it - don't even think about it. Do NOT hire K&K Construction - you will horribly regret it... In July of 2011, we hired K&K Construction to redo our driveway at our Littleton, CO reseidence. The work was completed during the period July 5-7, 2011 and the amount of $6500 was paid in full. The concrete began to show signs of defect as early as Oct 2011 and progessively deteriorated since then. Initially, K&K admitted that there was a problem with the concrete and repeatedly assured us that they would stand behind their product. My experience with K&K is that they are much better at delaying and denying than they are at installing concrete driveways. All along they assured me that they would stand behind their work and I much to my discredit believed them. At some point they decided they were not going to fix the problem and instead created an excuse that the 'ice melt' from the streets caused the problems. They also pretended to run a 'core test' - presumably to show that there was not problem with the concrete quality. The problems with the ice melt story are several fold including: 1. Problems with driveway began appearing as early as Oct 2011 and well before winter time, 2. The areas where concrete is in the worst shape is where the wheels of the car turn (right and left) - not where the wheels run straight or where the car sits in the driveway - presumably where ice melt would pool if it existed, and 3. How is it that our driveway couldn't survive one winter - one of the mildest winters on record - yet we're surrounded by neighbors whose driveways have survived intact not only this one mild winter but the previous 20 winters when the houses were built? The mythical 'core test': We never received the core test results so I believe it's safe to assume that they were never done or the test results were not what they wanted to see. I highly doubt that it was ever done and that he came out that day (8/24/12) and just drilled a little hole himself to delay things rather than hire an objective licensed engineer as required. Still waiting to see that official report. In my efforts to get this resolved, I have over 20 documented interactions including phone conversations and emails to/from K&K. I am happy to email this separately but several highlights are: 10/20/11: Initially reached out to K&K informing 'Dena Zerr' that there was a problem with the concrete. She said 'Kris Zerr' would follow up. He did not. Note - this is only 2-3 months after the job and well before winter. 4/27/12: Kris finally comes out to view faulty driveway and admits there is a problem and that they are trying to get the concrete company to pay for it. He says either way they will stand behind their product. Said Dena would call with to set a date to redo it. 5/22/12: After repeatedly reaching out to Dena she says that the redo date will be July 19-20. Additionally on this date, I emailed K&K with pictures of the deteriorating driveway. 7/12/12: Says redo scheduled for July 19-20 will have to be delayed as they want to do a 'core test'. States in email: 'We will still stand behind our work, but need to get this done'. I was naive at the time and actually believed her but looking back clearly this was just a delay tactic and any intection of them standing behind their work had vanished long ago... 8/23/12: Spoke to Kris as 'coring' has still not been done. He said he'd come out the next day to do it and also mentioned that the problem wasn't just us and that he had about $120,000 worth of business that was having problems with concrete from this supplier. He also said that the concrete company had gone out of business and that they switched to a new supplier with a better product -Martin Marietta. I have no idea if any of this is true just that this is what Kris told me. 8/24/12: Kris comes out and takes core sample himself. Oddly, he acts like the official core sample engineer was following behind in his car and just disappeared. So he takes it himself. Obviously, there never was an engineer with him. There are many more interactions to report but bottom line was Kris & Dena Zerr never produced any sort of core test report. Instead, they have discontinued communications. It is our family's objective that K&K re-do our driveway with proper concrete or refund us the $6500 paid for their faulty product. I am happy to speak live with anyone to discuss this - including staff at Angie's list, the BBB, K&K, the media and other folks who have had the misfortune to hire K&K. If we do not get a satisfactory resolution we will most certainly be moving forward with legal action. Feel free to reach out to me if you would like to connect and work together to hold K&K responsible.

10-11-2013 Since this company is listed twice as K&K Construction and K & K Construction I will post my comment to both. Don?t even think about using this company, you will live to regret it!! Believe me, I am not the only one who has ripped off by K & K or AKA K&K Construction, please do your homework first and check out the horror stories on BBB (15 BBB Complaints against K&K and 8 of them in this past year alone!!) which they were accredited last year but the BBB has since stripped them of their ?Accredited Rating? for a very good reason. Angies List has numerous horror stories abut them as well. I choose K&K Construction Inc. which was next to my highest cost estimate to replace my driveway and pour an RV driveway on 4-28-2011. Job cost was over $8000.00. I will list just a few of the problems I experienced with K&K Construction. It took me years to save the more than $8000.00 needed for this project and in return I received: 1)A finished concrete job with a poor look that two other concrete experts have already determined is defective; 2) Incomplete work; 3) I was overcharged; 4) No honoring of the Workmanship Guarantee 5) Time and frustration writing emails and sending certified letters which got me nowhere; 6) Money spent on postal fees 7) A refusal by K&K of my written NUMEROUS requests to meet me at the job site post job completion to discuss problems; 8) Less than a year after the job was finished, 61 feet of cracks in the driveway and more cracks in the RV slab not in control lines and 9) As of date of this writing, I have been unable to get K&K to repair or replace anything or to pay me the $558.42 settlement they offered me. 1. The most serious of the problems I had with K&K is, there are very visible ?Large Bumps? sticking through the finished surface of the driveway. To the day of this writing more than a year later, K&K has refused to repair, or replace the driveway. They also have refused to pay me anything, zero in terms or a settlement. 2. K&K Never Finished the Dirt Work. I had to order in dirt and install myself. 3. K&K charged me for more concrete than was actually poured for the RV Drive. I sent several certified and delivery confirmation letters to K&K explaining the cosmetic appearance of this defective driveway is unacceptable to me, not to mention it already has more than 61 feet of cracks and I wanted it repaired, or replaced which they refused. Also the opinions of my 3 concrete specialists that came to my house and looked at this driveway agreed workmanship was extremely poor and the size of the aggregate used was way too large!! I stated in my letters to K&K, I would accept a settlement of 1/3 the cost of driveway concrete only $1116.83 which they also refused. They did offer me a refund of $558.42 on November 14, 2011 but then retracted it and reduced the offer to Zero. Kris Zerr Owner of K&K Construction replied to me via email dated Dec. 1, 2011 and stated ?Your 1st plan to warn others about our company ? you better make sure that you don?t unlawfully slander us or we will have to seek compensation?. He ended it with ?You have your standard warranty and that is all we are willing to offer you at this time?. K&K provided me a written Guarantee, which included a guarantee on their ?Workmanship? but in my experience with K&K Construction, has proven they will NOT honor their own Guarantee or help in any way to resolve, what is in my opinion a very ?Defective Driveway? with ?Workmanship? issues. It has now been more than a year since the job was done and K&K stands firm to not help in any way. On August 17, 2012 I took K&K Construction to BBB Arbitration and I was asking for a settlement of $2630.34. This included a settlement for the ?Bumps? all over my defective driveway and also for reimbursement for the Rebar and wire mesh in both driveway and RV driveway due to Kris cut corners and failed to use ?Rebar Chairs? (which was in my work scope and Kris agreed in writing to use rebar chairs) so now all the rebar and wire mesh is laying flat on the dirt under the cement and not centered in the concrete, rendering it totally useless and waste of my $1645.00!! The end result was the BBB arbitrator awarded me a whole $390.00 dollars instead of the $2630.34. A company which K&K advertises through called ?Service Magic? was forced to pay me a $500.00 Service Magic Guarantee. I received this from $500.00 from Service Magic (NOT K&K) as they agreed K&K delivered ?Defective Workmanship? It is now obvious to me the BBB favors the Business?s rather than the homeowner. I regret not taking K&K Construction to small claims court instead, as I feel certain I would have received a fairer ruling, and if you take someone to BBB arbitration you sign away your rights to peruse him later in court. In my opinion, K&K approached my project focused solely on maximum profit and finishing as quickly as possible, leaving me with defective incomplete workmanship and a lot of money spent. I would hate to see even one more homeowner have the same experience as I did if they choose to hire K&K Construction. I would never use K&K Construction or recommend them to anyone as long as I live. I am extremely unhappy and dissatisfied with the job. I have never been taken by any contractor for as much money as I have from K&K ever, and I have used a lot of contractors on my fixer up home in Arvada. I?m sure owner of K&K Kris Zerr will post his very long response to this posting as he always does, and he will explain how his company did nothing wrong, and the job turned out perfect. Don?t you believe him for one second! I get to stare at my ?Defective Driveway? everyday now. I and the numerous other people would not take the time post comments against K&K if they were not true. The fact is, all the unfavorable comments you see on Angies List and BBB are just from those who took the time to post a comment, I would hate to think of how many other K&K victims there are that got ripped off like I did, but just did not take the time to post their story. In closing, if you read this and still use K&K, don?t ever say you were not warned!! See my posted picture as pictures don?t lie. $8000.00 worth of ripped off, very unhappy Arvada homeowner.

K & K Construction poured a "4000 psi concrete driveway" and front entrance in March 2011. We bought this house in June 2011. The concrete on the front entrance slopes TOWARD the house causing water issues. Worse, 19 of 26 -8x8 driveway sections have cracks, (not on the seems), some large, expanding, spidery, with chunks of concrete breaking off. This is with normal use. I requested a consultation with the owner of K & K construction in early September. He has refused to come and see the problem. Phone calls have been seldom returned and 3 promises to come seal the cracks have not been honored. K & K 's web site states a "100% guarantee for 1 year. I finally received an email from them stating they had no obligation to honor the guarantee as I was not the one who paid for the job. I contacted the previous owner who did pay for the concrete. He requested K&K honor the guarantee. It been 3 weeks with no response from K&K Construction. He has since refused to use them again. My experience with K&K Construction, 8442 Uinta st , Commerce City, co. has been a disaster.

Dena was very patient with us during the many changes we made to her bid, she was always accurate and prompt and gave us a very detailed bid. Prior to the job she came out to let us choose concrete and paver colors. Chris and his crew did a meticulous job over three days. The patio and driveway look wonderful. Chris asked for our imput on the details of the job and was responsive to our requests. His workers did beautiful finishing, and were friendly and polite. K & K was a pleasure to work with.
