Basement Water Leak

I had a damaging basement water leak at a rental property and called Pierre at Aquaseal. I was desperate to get the situation assessed. Pierre told me he would come to my rental property but would charge me $395.00 to assess the situation which would be taken off the total repair costs if I used Aquaseal. I stupidly agreed to pay because I was desperate and wanted to assess the cause of the problem. Pierre came to my rental property the following morning at approximately 7:30am and spent no more than 5 to 10 minutes (I was not home at the time - the tenents informed me of this). I had to phone Pierre two days following his visit to the rental property (he didn't call me) and he provided his opinion over the phone. I asked for an invoice and writen assessment of the cause and Pierre simply sent me a price list from his website. I appreciated that Pierre did not want to provide an estimate or opinion that didn't lead to future work however, I feel the 395.00 was not reasonable for what he did (a quick 5-10 minute assessment at the home and a phone call). Pierre recommended I hire a plumber to assess if the main drain was blocked so I followed his recommendation - the plumber found no issues and charged me another $300.00. The issue I have is that I had two other water leak repair companies come to the home and both charged $0 for the assessment/estimate and both provided a detailed quote in writing. It is interesting that the other two water leak repair companies provided a differentiate assessment to the cause of the leak. I am not saying Pierre's assessment was incorrect, but I am saying that the assessments these companies make are somewhat of a art and to charge 395.00 for an assessment and estimate is not reasonable and simply predatory to take advantage of people when they are in a desperate situation. I did write to Aquaseal to ask for a refund of $250.00 (hence paying Pierre $150 for his assessment of the home and phone call to me) because I felt his charge was excessive. I did not get a reply to my written request for refund.

(1) We are sorry you feel this way after a agreement made.
(2)The inspection was agreed on for $350.00 + hst 100 % refundable against future work.
(3) We notice that this customer is the husband of another review Lisa and Family in Whitby.
(4) The inspection was over a hour at the property for inside and outside (winter time much snow on property) including time with basement tenant (duplexed house).
(5) No Sure why homeowner Robert from Whitby insisted on Aquaseal doing inspection with out himself present against our recommendation,but Aquaseal rather had to communicate finding from property to owner at his place of work.
(6) As initially agreed Aquaseal is always still willing to refund against future work on this property.

Small basement leak

I spoke to Luc at Aquaseal. He seemed very knowledgeable and his estimate for what seemed to be a leaky tie rod hole was very reasonable. He agreed to come to my home Thursday morning. He was unable to show up as he is very busy, but he called in advance to reschedule to Thursday evening. I appreciate this as opposed to some others who simply might not call and not show up either. He looked at the tie rod hole in the evening and said "nope, it's not the tie rod hole." He then had a look in back of the house and said all I needed was a caulking job around my patio door frame. It cost me nothing. He shook my hand and was on his way! What an honest guy! Thank you, Luc!

Did not honour their warranty

AquaSeal completed our basement waterproofing in 2005 and we waited for 3 years before we did an overhaul renovation to our basement. We were satisfied with their services until this year when we discovered there was water on our cold room floor and there was water seeping out to our renovated area which caused our engineered hardwood floor to curl up. We asked AquaSeal to come to inspect and they told us that they were fully booked and could not confirm a time at all. In addition, they would charge a $250 inspection fee regardless of whether the water in the basement was due to defect in their waterproofing work.
So, beware of the so called "lifetime warranty".

The project that Aquaseal did for us was for the whole frontage and the right side of the house. It was not as its response saying that it was not an area that it did. What I found unacceptable was its refusal to come to see the issue and requested for a $250 for the inspection fee before it would send someone around. Very unprofessional!

not sure why i am only seeing this review today April 20 -2013 as this review is dated Dec 04 2012.Have no idea who wrote this or even if if its "REAL OR NOT" Sounds like a possible (IF REAL) or (Fake) customer or (Posted by a competitor which has happened before). who has a possible leak in area not addressed by Aquaseal before.Some people ask and or assume if we fix a crack in one location and in future years they have a leak in the same """" area """" that we warranty the complete length of wall 30 feet long.

Crack in basement wall coupled with damaged exterior down spout

At the tail end of a mold remediation, there was a really warm period with the resultant snow melt finding its way into my basement through one sizable crack. This was the culprit for all my mold problems.

Pierre (owner/mgr) bent over backwards to get my problem fixed quickly when I called (somewhat hysterically I might add--water was coming in as we spoke).

The crew (Rudy and Axsel) arrived exactly on time and were done with the repair within an hour (~7 foot crack floor to above ground level.

Excellent work was done on a timely basis. Time will tell if this seal holds but at this point in time, go with these folks. I'm glad I did!!

Remedy water in basement

Two years ago, I posted a very favourable review regarding how Aquaseal fixed the water coming through floor cracks in the basement. Less than two years after their "fix", the water returned -- worse than before. We called Aquaseal, however the representative simply suggested that we spend much more money and install a more extensive system of weeping tile pipes under our floor, even though the first system had clearly failed. We sought the opinion of other local waterproofing companies and one diligent company first investigated the inital work done by Aquaseal. Apparently, Aquaseal's solution may have worked initally, but Aquaseal used a poor quality connector and didn't line up the weeper properly to the main drain. The competitor showed us how a block of calcification had formed at the connection elbow leading to the main drain. This led to a build up of water under our home over two years and the subsequent flooding we had to endure. The other company saved us lots of money. Aquaseal may have had the right solution, but their poor execution cost us more money, headaches and time.

(1) We are sorry you feel this way after 4-6 successful service calls to your home for various leak issues and repairs done by Aquaseal over a number of years. (2) Just to note this complaint from Lisa And Family in Whitby is Married to Robert from Whitby complaintant (3)There was a also a inspection done by Aquaseal Rep in response to water coming up through basement floor furnace confined area only . (4) It was further agreed to deal with a minimal underfloor drain system for this immediate area only (Cost Reflected Small Area only indicated at that time) . (5) Some approx 2 years later Aquaseal was called in again for flooded finished basement .(6) Aquaseal noted to customer that there was a serious issue with the complete house weepingtile system not functioning as intended as so much water was coming up through floor throughout.(7) Aquaseal gave pricing to solve weepingtile problem and customer never responded back.
(8) Complainant stated we used a poor quality fitting (9) Response is we never buy or have bought a lower quality fitting.(10) Sometimes a story is in fact a story what another competing contractor may tell you.
(11) Aquaseal again is sorry for the way you feel which is solely based on what another contractor tells you
(12) Aquaseal is willing at any later date provide any prospective buyer or Real Estate Agent a complimentary Inspection for your property which has a value of $550.00 +hst

Basement Leak

I had a water deluge in the basement starting in August...behind the drywall and onto the floor..a real mess..to top it off it looked like it was coming from where a brand new expensive deck that was just completed...I called a company that said they could do it by digging outside and tearing down the brand new deck....I don't think so!!!
...I called Aquaseal and Rudy came out to get a look....unfortunately it had not rained for a while so there was no new wetness....Rudy did not want to take out drywall without being sure
so he suggested that I run the hose on it after a couple of days of dryness and make sure it was a crack and not the patio doors..
I did that two days later and lotsa water....Called Aquaseal back
and they sent out a tech right away...
Dave came out right at the agreed time..took a look around and found the problem with minimal disruption to the drywall...he fixed the crack by injection ;the entire job was carried out in a truly
professional manner.I am really impressed with Aquaseal and recommend them to anyone with this problem..thanks to service man Dave..
