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

Highly recommended. They were very efficient and reliable. All "paper works" were processed and done electronically. Prompt and professional with their responses. The waterproofing worked and the water retest from HDB passed. yey! we were spared from fully renovating our toilet which would have brought unnecessary inconvenience and help us saved money. Thank you!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

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

I engaged Prima Seal Waterproofing to do my kitchen’s toilet flooring on 12 Mar 2018. Their service is wonderful! Punctual, polite and job done nicely! Jason from Prima Seal is the person whom I liasie with all the while in this project. He is helpful and will explained patiencely to me when I have doubts or problems as this is the first time I am doing this and I know nuts about it. Yesterday, 17 April 2018, HIP (HDB upgrading project team) came to my house to do the waterproofing test and guess what, we passed with flying colours! Thank you, Prima Seal and Jason for all the help. Good Job and well done!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

Michael is very professional in handling my bathroom leakage issue despite my challenging neighbor. He offered me with a good economical solution which save my hassle from doing hacking on the floor. He is a responsible person who took his personal time off to monitor the water test in the bathroom following the repair work.His operation team works efficiently (although there's some minor white spots on the flooring and toilet bowl but they are fading over time).Overall, I am happy with the service given by Michael and team. Will definitely recommend them to those in need.read more

Contacted Prima Seal to do bathroom waterproofing after failing HDB water test. Mr Leon came to inspect the bathroom and offer quotation. They arranged for an appointment within a week and arrived promptly on the stipulated time. Infusion process was explained to us thoroughly and carried out professionally. As we had to do 2 bathrooms, they advised us to do one at a time so that we can still at least use 1 bathroom in the meantime. Due to some community "disagreements", Prima Seal willingly conducted a 2nd round of infusion just to satisfy their demands. They did their work until all parties were fully satisfied with the waterproofing results. After each infusion process, the crew ensured that the bathrooms were properly cleaned and no mess was left inside the house as well. These guys take pride in their work!I'm glad that I engaged them to do the non-hacking version of waterproofing. It eliminated any construction and now I'm very, very pleased with the results and service provided. One of the very few Singapore companies that strive for 100% customer satisfaction.read more
