In Mansion House we are particularly good at drain surveys and investigations
There’s no doubt about it, moving home is expensive, and Mansion House Home Buyer’s structural surveys used to be relatively straightforward.
A building surveyor would attend the Mansion House house you were going to buy and undertake inspection, ranging from the entry level ‘valuation’ up to the ‘full structural’, none of which were cheap. The majority of buyers would opt for the entry level and least expensive option their mortgage lender would accept in Mansion House London EC4N. Against a backdrop of litigation and a compensation culture, surveyors have had no choice but to add disclaimers about anything he or she can’t actually see or inspect, especially underground services like drains.
Hence the recent additional need of a specialist drainage survey for Mansion House properties.

Unblock toilet
“Unplugging the toilet went really quickly, such a nice informative man.”
Clearance of blocked soak away
“Several people looked at the issue, suggesting that significant works may be needed to resolve. Spoke to Happy Drains, explained things well over the phone, suggested it may be a simple job to unblock it. Arrived quickly, did the job and all seems well. Very pleased “
sink waste pipe blocked
“I called happy drains with blocked sink waste, the receptionist arranged for the technicians to attend the following day informing me they would call me 30 minutes prior to arrival. The technicians did call me 30 minutes before arriving. They understood the difficulties involved with the blocked waste as the access was challenging and with patience and experience they unblocked the blockage. The guys were polite, tidy, on time, and knowledgeable. Will defiantly use happy drains again “
Unblocking drain
“From when you call them, you are dealing with a real person and with that comes efficiency. Very polite on the telephone and also the drain engineers on site were very polite and just got on with the job. They showed you the unblocked drain before leaving the site and explained what I would receive in the report via email. Thoroughly recommend them and very good value. For the amount of crap they have to unblock each day, the service is spotless.”

Illegal connections in Mansion House and other dodgy works
During the course of any survey we will take the opportunity to make sure that all your drains are connected appropriately.
The causes of illegal Mansion House drainage connections range from innocent DIY plumbing mistakes to poor building practices. We regularly find washing machines discharging to the London rain drains and rain drains that discharge into a sewer some times because some Mansion House home owners have been unaware of the differences between surface water and foul waste drains. However the water company serving Mansion House will demand to put these issues right at your own cost.

Had issues with blocked drains
“Extremely professional service proper old fashioned service solved the issue within an hour and wasn’t expensive would highly recommend Many thanks happy drains”
Outside drain unblocked
“I called Happy Drains to clear an outside drain at my father's property, which had become blocked. The friendly lady that answered the phone very helpfully managed to get someone to come the next morning. I received a call prior to the workmen arriving, which was reassuring. They were friendly and very efficient; 25 minutes after they arrived the problem was resolved; brilliant! I would highly recommend this company.”
Blocked external drain
“I had a blocked drain (external to the property). I previously had someone to look at and they explained that the drain had likely collapsed and quoted to fix (over £1k). I thought I would double check. Happy Drains visited and drain was clear within minutes (blocked trap) with no requirement to dig up garden and replace drains (or use a camera). 60 day guarantee inc in case it blocks again. Engineer was polite, friendly, cleanly dressed and professional. As he said 25 years of experience. Great job, highly recommend (and I will be recommending further).”
Unblocked drain
“I highly recommend Happy Drains. I contacted them on behalf of my elderly mother. I explained that I was unable to meet them at my mother's property so they sent me photographs of the completed work. I was extremely happy with the service provided by all the staff involved. “
