Here is our ‘review’ for the website 
Reviewer: John & Kathy Thompson 11/2/2015
Cottrell Basement Waterproofing/Denny came to meet with us and by the end of the same week our basement was completed. The team finished in the time that was proposed and the basement was very clean when they left AND the total price was less than expected. We would highly recommend anyone talk to Denny when needing to ‘waterproof’ their bases.
Look no further than Cottrell
Reviewer: Jonathan C. 4/26/2014
“If you’re considering basement waterproofing, look no further than Cottrell. Their system is second to none, the work is high quality, and the crew is specialized, experienced and knowledgeable. Denny and Dan explained the process clearly, and were very transparent from the first contact. During the in home consultation, they actually give a presentation detailing every step. I knew nothing about basement waterproofing, sump pumps, or drains before, and I found it to be very informative. Their process made me feel very comfortable to make the investment. There were no surprise costs. I paid exactly what the job was quoted, and not a penny more. The crew was punctual, and worked extremely hard each day. They took care to protect the finished areas of my basement from dust, dirt, and debris. Denny even sent a professional cleaning crew over when the job was done. Nice touch! All in all, the small investment I made with Cottrell waterproofing has given me piece of mind for the future. I no longer fear those days when the rain just won’t stop coming down. Not to mention the fact that the Cottrell Waterproofing system just added instant value to my home. Thanks Denny.”
Wet basement for 20 years
Reviewer: Christine A. 4/17/2014
Our basement has been getting wet most of the 20 years we lived in the house. Finally we called Cottrell Waterproofing. They did an excellent job in a timely manner. Worker’s were very knowledgeable and most pleasant . And yes, our basement is Dry after 2 days of rain. Thank you I would recommend Cottrell to anyone in need of waterproofing.
We don’t have to worry anymore about a wet basement
Reviewer: Ron and Pat P.
Thank you and your employees for the excellent job you did at our home in Hummelstown. Your workers were very professional and the work was done in such a timely manner that my husband and I were surprised at how short at the time it took to finish the work. The cleanup that they did was amazing! I would definitely recommend your company to our friends, family and co-workers without hesitation! Thank you again for the professional way it was handled. More importantly thank you and your workers for all of the hard work that they did to fix our problem and give us peace of mind knowing that when bad weather hits we don’t have to worry anymore about a wet basement!
Very Professional
Reviewer: Marilyn P
From start to finish they were very professional. On Their first visit they explained exactly what needed to be done. They came back on our timeline and performed the work in three days as quoted. We were not here while the work was being performed and were very pleased upon our return to find that everything was done to our satisfaction.
Prompt and Courteous
Reviewer: Denise T
I received an estimate from Cottrell Basement Waterproofing to have as sump pump system put in the basement. They were prompt, courteous and professional. I have done some research on sump pumps and I got an estimate from from somebody else but they were offering more work for the same price.
Punctual and Friendly
Reviewer: Anthony H
he salesman was excellent in his presentation and explanation of the work to be done. The installation team was punctual and friendly.
It was amazing
Reviewer: Michael S
He pointed out what was wrong, and why it was wrong. He said it would take 4-6 days to get the job done, and it only took three. They came in and told me what they were going to do, and they did it. You could recognize their job right away when walking into the basement. It was amazing.
It looks great
Reviewer: Betty M
I had moisture coming thru the basement floor since early spring. Denny’s people had installed my sump pump last year & Iwas happy with their work, so I called him to see what he could do with the floor. After I told him how bad it was, he suggested putting a couple coats of apoxy on. He had someone here within the week. It took a couple days to finish. It looks great; he also had Brandon put these sprinkles on to prevent slipping. He also installed a fan to help circulate the air when it gets really humid. I was told the apoxy is very expensive before they did the work. I am very satisfied.
Great Attitude
Reviewer: Donald D
They dug a trench in the floor down to the footer. They put in some pipes and covered it with concrete. They were able to fix basement leak.
Before starting, they covered all of my stuff with plastic covers and made a reasonable effort to keep the concrete dust off all appliances.
Trenched around inside basement wall down to footer. Buried drainage pipes in trench. Removed old sump pump, dug a new sump pit in a different location, installed dual sump pumps in new sump tub and installed cover. Filled in old sump hole and concreted over top. Concreted over trench to cover same. Installed “Ez Breathe” vent system. Cleaned up mess. Tested both sump pumps.
Fogged walls with a mold/bacteria chemical that got rid of any musty problems.
I had had water damage to drywall and had it removed prior to the start of job.
It was a reasonable price. They prompt, courteous, reliable. The work was great. This is a pretty good work crew. They had a great attitude. It is a very messy, invasive procedure and they took time to cover everything and clean up very well.
All things considered, the job went rather well and was completed in two days.
If anyone is considering a job like this by ANY major basement waterproofing company, be forewarned that this is a noisy and dirty procedure but the end result is worth the trouble.
They will be working with jackhammers and it is very noisy -To quote the often misquoted line-“You can’t make an omelet without breaking eggs”.
Recommend Them Highly
Reviewer: Doris L W
Told my neighbor about cottrell waterproofing from seeing it on Angies list,so I went to their web site and checked out the reviews. I advised my neighbor to call them, because so much water kept coming in her basement that one wall was leaning in and breaking all its mortor holding blocks i place. My neighbor called them and they came and gave an estimate. On august 22 2011 they came and started the work they were very professinal and completed the work by august 27 2011, just in time for hurricane Irene the basement is completely dry and we are now have drenching rains and her basement is dry and she is very happy. I would recomend cottrell waterproofing to everyone who has water in their basement. Cottrell does excellant work I would recommend them highly
This guy is good!
Reviewer: Betty D
I had 3 other big name Waterproofing companies in to quote our basement. We had a small stream flowing in our home it seemed like. We were terrified that we wouldn’t be able to repair this due to my husband being out of work. Denny Cottrell jr. arrived on time to give us a estimate. He was polite and very helpful. Cottrell basement waterproofing was $3700.00 cheaper than the other companies! And he even installed a 8″pope instead of a small 4″pipe. We saved money while getting a better system. The crew was protective of my furniture and courteous the entire job. When they were done I was surprised that my basement was cleaner than when they arrived. Denny called us 2 weeks after the system was installed just to check in. This guy is good! I will refer his company to everyone! Good Job Cottrell Basement Waterproof
Would do business with them again
Reviewer: Dylan P.
I had mid-atlantic waterproofing and another company company come to give me an estimate. I was not going to get my basement waterproofing done because of the high prices. Then I called Cottrell Basement Waterpoofing. I made an appointment for the same day. The owner came out himself and gave me an estimate half the price of mid-atlantic and $4000.00 cheaper than the second company. Now I could afford it. Now I have a dry basement. Would do business with them again. Thanks alot.
Knowledgable Crew
Reviewer: Tammy M.
I had two other basement waterproofing contractors come out to look at our basement. Cottrell Basement Waterproofing was by far the most affordable. The crew was very knowledgeable and Denny did not use high pressure sales pitches. I chose Cottrell Basement Waterproofing due to their outstanding reputation. They allowed me to choose my own date and time to come to my house to complete an estimate. They finished the Waterproofing of my basement in 3 days! all the workers were very clean, professional, and friendly. After all their great work and hard work I now understand why they have such a great name for themselves! The quality of the work greatly surpassed the price. Cottrell Basement Waterproofing was well worth the small investment. If you have a wet basement you need Cottrell Basement Waterproofing.
We had a good feeling…
Reviewer: Jeff & Laurie L.
We had a good feeling about Dennis Cottrell Jr. The Moment we met him…And he didn’t let us down! He came out promptly to give an estimate and started to work on our old, very wet basement the next business day. Dennis and his crew were tireless workers who did a superb job waterproofing our basement at a reasonable price. We highly recommend him
Highly recommend this company to everyone
Reviewer: H. Stark from Dresser PA.
LET ME TELL YOU FIRST WE ARE RETIRED. WE HAD A FINISHED BASEMENT THAT WAS REMODELED IN NICE OAK WOOD. WE HAD THE REMODELING DONE 12 YEARS AGO. THE CONTRACTOR USED DRYLOCK PAINT AND TOLD US IT WAS WATERPROOFED. WE STARTED GETTING WATER IN OUR BASEMENT AT THE REAR CORNER. SO WE CALLED A LOCAL PRO. HE TOLD US WE HAD A WATER ISSUE PLUS A MOLD ISSSUE NOW!!! OUR BASEMENT HAS OVER $43,000.00 WORTH OF OAK WOOD WORK. THATS THE MATERIAL COST. NOT THE INSTALLATION OR THE COST WE HAD TO PAY THIS CONTRACTOR TO REMOVE ALL OF IT. MOLD HAD DESTROYED IT. AFTER I PICKED MY HUSBAND UP FROM THE FLOOR FROM THE CONTRACTORS COMMENT, WE STARTED CALLING AROUND.
WE CALLED SEVERAL LOCAL AND NATIONAL COMPANIES. ABOUT 4. THEY ALL SHOWED US NICE PICTURES AND SUCCESS STORIES. PROMISED US THE WORLD AND HUGE SAVINGS IF WE SIGNED RIGHT THEN AND THERE! I MEAN HUGE. WELL WE DON’T REALLY CARE FOR PRESSURE SO WE STARTED LOOKING AGAIN. OH, AND THEY ALL WANTED TO INSTALL 3 OR 4 INCH ADS PIPE AND 1/3 HP PUMPS. SO WE HEARD SOME THINGS ABOUT THIS COTTRELL BASEMENT WATER-PROOFING. HOW THEY WERE OFFERING SOMETHING REALLY UNBELIEVABLE. WE FIGURED HE HE WAS WILLING TO DRIVE HERE, WE WOULD LISTEN TO WHAT HE HAD TO SAY. FIRST LET ME TELL YOU……HIS PRESENTATION WAS ONLY 20 MINUTES! HE EDUCATED US ON WHAT HAS HAPPENED ALREADY, AND WHAT WILL HAPPEN IN THE FUTURE. HE SHOWED US THIS MASSIVE PIPE. WE LAUGHED!
MY HUSBAND SAID , “DENNY, ISN’T THAT ALITTLE OVERKILL? ” AND THIS GUY DENNY SAID SOMETHING THAT SOLD US ON THE SPOT. DENNY SAID, ” MR. STARK, IF I PAID $43,000.00 FOR OAK WOOD, PAID TO HAVE IT TORE OUT, AND NOW HAVE A WATERPROOFING CONTRACTOR HERE TO MAKE SURE IT NEVER HAPPENS AGAIN……..OVER-KILL WOULD BE WHAT I NEED FOR PEACE OF MIND. ” WE CONTRACTED WITH COTTRELL BASEMENT WATERPROOFING ACOUPLE MINUTES LATER. THEY OFFERED A BETTER SERVICE THAT WILL STAY WORKING IN THE WORST CONDITIONS POSSIBLE. I DON’T KNOW HOW HE WAS LOWER IN PRICE THAN ALL OUR ESTIMATES. HE USED A LARGER MORE COSTLY PIPE, AND HIS SUMP PUMP WAS ALOT BIGGER AND COST MORE. ALL IN ALL WE HAVE A SYSTEM THAT WAS CHEAPER THAN THE OTHERS, AND IN THE LONG RUN WILL COST US NOT EVEN A DIME! THAT SAYS IT ALL. AS YOU CAN SEE , WE HIGHLY RECOMMEND THIS COMPANY TO EVERYONE!
Trustworthy and Reliable
Reviewer: Ron H
After contracting with Cottrell for a french drain installation, I fully expected to have to wait several weeks for a heavy, soaking rain to test the system out. It so happened that Tropical Storm Lee hit Central Pennsylvania during the final days of our system installation while the crew was still in our basement. While the drain pipe and pit installation were complete at the peak of the storm that Wednesday, our sump pumps were not yet installed. When our newly installed system and pits began rapidly taking on water, the Cottrell crew sprung into action and quickly placed the sump pumps into the pits and rigged piping out our basement windows so that the system would not overflow! Not only was this a great and unexpected load test of the system, their quick action prevented water from entering and further damaging our basement. When the Cottrell team was unable to return Thursday due to the unprecedented flooding and hazardous road conditions, Denny called to check in to make sure everything held up overnight. From the quotation to the install to the follow-up, I have been impressed with Cottrell at every step. In a confusing and crowded industry with so many fly-by-night companies, franchises, and sub-contractors – I am happy to recommend a local business, Cottrell Basement Waterproofing, to any person looking for a trustworthy and reliable solution to basement water issues.
Denny saved us a fortune
Reviewer: D. Martin
Denny saved us a fortune We had a small but persistent leak where the water pipe from our well came into the house. I finally decided to fix the problem instead of trying to patch it up. Denny’s crew uncovered the pipe with minimal interference to landscaping. They discovered the pipe was cracked and then learned that that style of pipe is no longer manufactured. The word plumbing supply houses gave Denny was that the entire pipe to the well would have to be replaced at a cost of thousands of dollars. Denny wasn’t willing to take that for an answer but was willing to think “outside the box.” He found a solution for just a few hundred. We are very appreciative, Denny, and highly recommend you to anyone who wants the job done right.
Thanks again for the great service.
Reviewer: D. Simmons
Hello Denny, It’s been a few months since you and your team were here to waterproof our basement and we wanted to thank you for the awesome job. Before you waterproofed our basement we were seeing occasional trickles of water seeping in after long or hard rains or during snow melt. The basement always smelled musty and the walls were often damp. We called a few waterproofing companies that we’d heard advertised, including yours, for estimates. By far, your price provided us the best value but what truly sold us on your service was the step-by-step explanation of the process you would apply to correct our particular situation. Your crew did a great job protecting the work area to minimize messiness and did a great job on the clean-up afterward. Since completion we have had no water in the basement, the musty smell is completely gone, and the walls are no longer damp. Finally, we can enjoy the basement and plan a man-cave, or a sewing room. I guess we’ll arm wrestle for it! Thanks again for the great service.
$900 lower than other companies!
Reviewer:
We had Cottrell Basement Waterproofing install our Egress window. Their price was $900.00 lower than other companies. Customer service was the best we have ever encountered!
