Investigate and Clear External. Blocked Drain
Was a great experience. Easy to organise. A touch late on the day but was kept informed.. Joe was great where he turned up. Explained everything and didn't upsell unnecessarily. Was efficient, polite and friendly. Great all round. Nice report/record at the end of it. Great contrast to some of the trade service experiences that you can have quite often.

Called Happy Drains as although drain wasn't blocked it was smelling and there were drains flies. Excellent communication from all, keeping me informed as to time etc. They came the next day, on time, and hosed the drains out. Very nice guy, did the job efficiently, left drain clean and running freely, and within a few days 99% of the drains flies were gone. Highly recommend.

I used Happy drains to survey the drains of the house I bought in Kew Gardens SW London. From the initial phone call they were professional and efficient and friendly. The guy turned up on time, very professional and knew his stuff. Turnaround of the report was super quick, it was comprehensive, and included video and was easy to share with the estate agent . It gave me peace of mind to continue with the purchase. They were competitively priced and I would highly recommend

Tommy & Gordon Happy Drains' amazing guys, saved me from another drainage company I called who overcharged for their incomplete services and wanted several £1000's! for further work!
