Our Care

We aim to help you determine the source of water leakage, providing high-quality, environmentally friendly, and cost-effective waterproofing solutions for both interior and exterior.

Locating the source of the leakage is not an exact science. It is a process of elimination due to the fact that leakage may have several contributing factors and may not always be the direct result of one specific problem associated with the exterior.

We will trace for water leakage issues and notify our customer whether the root cause is from flooring waterproofing, concealed water pipe. Let us solve your problem without worry, we will give all our customers a peace of mind.

I contacted Prima Seal for chemical treatment of my leaking toilet which they were quick to response on all my queries and appointment arrangements via whatsapp. Unfortunately after the chemical treatment, the leak still persist, but Prima Seal stepped up and arranged for PU injection in my neighbor's toilet downstairs at no additional charge, and my problem is now solved. Will definitely recommend their services.read more

Got Prima Seal Waterproofing to fix the issue of leaking at my lower floor neighbors’ 2 toilets ceiling.They did chemical proofing on both my toilets’ floors. Waited 2 weeks for complete drying n then did water testing where both my toilets were flooded for 4 hrs. There was leaking still at the neighbor’s master toilet. They came on at agreed date/tile to now do chemical injection into the ceiling of my neighbor’s ceiling which took abt 2-3 hrs. Did a good job to ensure it is clean. They came up to check on my toilet bowl to ensure the chemical injections did not choke it. We waited about 10 days for complete drying and just did another water test again as above ie 4 hrs of flooding my master toilet. All leaking at my neighbor’s master toilet ceiling is solved. This happened today. All good and very happy with the work done. Prima Seal staff are prompt, friendly, informative and punctual. Money worth spending n better re-tiling which will be damn dirty n dusty n stressful for everyone. So I will recommend them for your floor leaking problems.read more

Our Master bedroom toilet was leaking to the unit below us. HDB only option was to hack my toilet. We get our previous renovation contractor to ratify the problem but was unsuccessful despite several attempts. Their final option was also to hack our toilet. We go through the internet of many waterproofing specialists, and we found good reviews and specific information of Prima Seal's Waterproofing. We decided to get them to help.The team came, surveyed the situation and provided professional advice to us and the unit below.The workers carried out the treatments in a very professional, polite and efficient manner. They even went to the unit below for further check after the chemical treatment and follow up call and inspection.We would strongly recommend Prima Seals Waterproofing for any of your water leaking problem .read more

We have engaged PrimaSeal Waterproofing on July2018 during HDB HIP in our block. Responsive with all mu queries. However, the tricky part is I need the engagement of my neighbour downstairs which is not very cooperative. 😂 PrimaSeal solved the water leak on our master bedroom toilet and it saved us from hacking. Highly recommended, will surely engage them again in case I will encounter water leak. 👍🏻read more

My common toilet failed the HDB HIP water test and I did not want to hack my toilet to rectify the water leakage problem. After having read many good reviews and also getting specific information from Prima Seal's website, I decided to engage them to help me.My water leakage problem was a bit challenging and it took three treatments to finally rectify it and help me pass the HDB HIP water test. Throughout the process, Jason and his team were patient, committed and provided professional advice and competent service. The workers who carried out the treatments were polite and efficient, and always kept the place clean after finishing their work.I would highly recommend Prima Seal if you need a reliable company to help you with your water leakage problem!read more

Right from signing-in the contract for our flat - we got a Water (soi) flat.The day we singed - heavy rain, 2 days after moving in - the first flooding because one tubing of a water heater was loose. Two years later the warm water tubing of the bathroom burst and as the sink was sealed of by the developer we got ca 4000l water flooding our living room.A few weeks later we found out that we could see water marks on the false ceiling of our kitchen and some other places. The roof got repaired by the Condo Management - but the water marks of the kitchen became larger. At the same time when we saw water dropping on the kitchen floor, (after careful analyses) coming from our balcony above, we got the information that there was a water dripping in the master-bedroom below of our roof garden. We started to search round to rectify the problems - but with the answers of the first contractors who came and looked at them we did not get a reasonable problem solution.Then I found Prima Seal via the Internet search and Jason Kuah analyzedour situation and we got for both problems a solution. The roof garden - 5 Layers Waterproofing with Fiberglass worked immediately but our upper balcony above the kitchen was too extreme damaged over time and the leaking started again a few weeks later. After one extreme heavy rain the water burst through and the kitchen was under water. Prima Seal arranged the rectification with quite some extra work including applying a new concrete layer to stop the water flow and as we saw two months later that that now worked they fixed the big hole of the artificial kitchen ceiling very nicely including painting of the damaged area Summary: Analyses of the problems - very good with personalized solution. Nice After-sales-support till the problem got solvedWould wish other contractors would do the sameGerhardread more

I am writing this to share a great experience on how I got back all my lost cryptocurrency tokens from cryptocurrency theft and fraud. I was really down when I got to know that all my efforts investing with this crypto broker is a sham. I use to think that when I cash my profit, I will live the life I have always wanted for myself so realizing everything was fake really broke me down. I heard about a CYBER GENIE [hacker], the best in cryptocurrency assets recovery. I contacted them with high hopes of getting my crypto asset recovered and they didn't disappoint me at all. They provided me with adequate and efficient service that resulted in the effective recovery of all my stolen crypto assets. I am extremely grateful to them for their expertise, excellent service and a job well done. And if you have also been a victim of cryptocurrency investment fraud, I highly recommend CYBER-GENIE. They are the best in this business and he will help you recover your assets back 100%..For guidance: ( Cybergenie@Cyberservices.Co m ) W/A: (+1) (252)(512)(0391)read more

Used them for the master toilet waterproofing treatment as the neighbour complain of water leak even though it was a dry toilet that we didn’t use at all. We do not wish to go through hacking , too much of hassle and mess. So we decided to try Prima Seal treatment. And Prima Seal solve the problem! Hdb called to say case closed. Leaking has stopping. They are very prompt in service and did follow up with us promptly. Appreciate their work!read more

My maisonette went through a hdb upgrading exercise recently and it caused my kitchen ceiling to leak from the bathroom upstairs. The ceiling had leaks in the past and I did PU injection to cure the issues. After upgrading of the spalling concrete at the same spot the leak happened again, the hdb contractors did not do much to help except to explain and push away the issues unless I hack the floor and redo the waterproofing.. I read about Prima Seal on the internet and took a leap of faith to call them. At first my family members were against using them as they require full payment before the works but I still went ahead despite the disapproval... like I said leap of faithWhy- they are punctual, on the dot at the appointment time- they explained to me the works to be done, what to expect and secondary measures if things doesn’t go as planned.- transparent on the costsI did the flooding thingy 3 weeks ago and the ceiling still leak so they did PU injection today. The situation was sticky but the guys were serious with their business and genuine people. They took my calls promptly and the after service was prompt. These guys are legit. Hopefully I don’t have to call them again!read more

Neighbour below complained of slight ceiling leak. After calling Prima Seal, they were prompt to send a specialist to check and there was indeed slight leak. The chemical infusion process (basically flooding the bathroom floor) was done on another day which took a few hours and then it was cleaned up properly by Prima. After few weeks, water test conducted by HDB contractor was passed (meaning no more leak). Great job to Prima Seal and saved me the hassle of having to hack the bathroom floor and replace the waterproofing membrane. Highly recommended!read more

Did some search on internet on waterproofing services and chance upon PrimaSeal. Compared prices and find PrimaSeal prices reasonable. The technicians did a survey first before providing a quotation. They are young folks but experience and know what they are doing. Half a day's job and the waterproofing on my side wall and second floor ceiling latch was completed. The waterproofing method used is great.. no hacking, just chemical infusion to seal up the cracks and pores on the concrete. No more leaking during heavy rain and we are very satisfied with the work.read more
