Dec 2013 – Christmas was drawing near, and our drainage contractor was letting us down. We approached Capital who happily agreed to cover all drainage emergencies during the Christmas period. We were so pleased with their service and brought them on board to cover all drainage related issues for our Kent based Housing Association contract. We can totally rely on Capital; they are a loyal, professional, and reliable contractor and are experts at anything drainage related.
Very helpful, reliant, great work ethics. Brilliant.
I wanted to thank you and your team for sorting out the drains. As you know this is has been an ongoing problem for many years and to finally have it sorted for good, and no terrible smell every time you run water with drains backing is a massive relief.

A few things that will help put your mind at ease.
Our customers often have questions about drainage surveys. Here are some answers to the most common questions we get.
Who pays for the repairs?
The current owner may wish to either carry out the repairs prior to exchange, or you may wish to negotiate a reduction in price based on the cost of repairs.
Can you fix the faults?
With over 30 years experience we have the capability to carry out almost all drainage repairs.
Who stands to benefit from a drainage survey?
You the buyer, to give peace of mind and to prevent the additional expense of sometimes costly drainage repairs once you have moved in.
When should these surveys take place?
Any issues that are uncovered can slow down the buying process, so the drainage survey should take place as soon as possible before the exchange of contract.
How can I be sure that the drainage surveyor is NADC certified?
The NADC supplies certified surveyors with a certificate and ID card. Always ask to see these so that you can be sure that your surveyor is certified.
Who is responsible for ensuring that a drainage survey is taken?
Ultimately, repsonsibility lies with the buyer, but the building surveyor should prompt their client to have a survey completed.
