Best Waterproofing SG fixed a severe roof leak that 3 other contractors couldn't solve. They identified the root cause in 30 minutes, completed the job in 2 days, and the roof has been perfectly dry for 2 years!
Called Monday, inspection Tuesday, waterproofing done Wednesday — no hacking, no mess! The downstairs neighbour confirmed the seepage has completely stopped. Excellent team!
As a property agent, I regularly recommend Best Waterproofing SG to my clients. Professional, punctual and their 10-year warranty gives buyers huge confidence. My go-to contractor!
They waterproofed our condo balcony and master bathroom. Very neat workmanship, competitive price, and the team cleaned up after themselves. Will use them again for my other units.
Our shophouse external wall had severe seepage for years. Best Waterproofing SG did crack injection and elastomeric coating — stays dry even in monsoon rain!
Quick response, honest assessment and fair pricing. No upselling. Basement carpark waterproofing was completed on schedule. Great value for money!
