DrainWise Testimonials

Stephen Warrington

DrainWise responded rapidly to my need, which involved investigating and clearing external drainage channels and soakaways. The work was undertaken thoroughly using fit for purpose equipment, including a camera to examine pipe work internally. The service was professional and friendly, and unhurried, with thoughtful expert advice given about the improvement of my drainage situation. Excellent.

Lisa Lewis

Spoke to Jonathan over the phone who was very helpful, and despite it being mid afternoon was able to send someone out that day to unblock our drains. The guy in attendance was there past 9pm and did a great job - super quick, excellent service provided, thoroughly impressed!

Sam Edwards

DrainWise attended my property as we had a blocked toilet. Grant the engineer was efficient and very polite and we were back up and running in no time. We were very impressed with the service that was provided.

Ruth Lewis

Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

Luke Taylor

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

John Robinson

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up.

Alison Taylor

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy.

David Stemp

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Jess Slater

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks

FAQs

What causes blocked drains?

Blocked drains can be caused by a range of issues, including fat, oil, and grease build-up, wet wipes, food waste, hair, soap residue, tree root intrusion, or collapsed pipework.

Recurring blockages may indicate a deeper structural problem within the drainage system, which may require a CCTV drain survey to identify properly. In all cases, we can help.

Who is responsible for blocked drains?

In many cases, homeowners are responsible for drains within the boundary of their property, while shared drains and public sewers are usually maintained by the local water authority. For commercial properties, responsibility can vary depending on ownership and drainage layout.

If you are unsure who is responsible for a blocked drain, our team can help identify the issue and advise on the next steps. You can also read our guide on blocked drain responsibility for more detailed information.

Do you offer emergency drainage services?

Yes, DrainWise provides emergency drainage services for domestic and commercial properties.

Whether you are dealing with a blocked toilet, overflowing drain, sewage backup, or flooding issue, our team can respond quickly to help make the area safe and restore proper drainage. Call us 24/7 on 01295 597 961 or explore our Emergency Drainage Services.

How quickly can you attend?

Response times can vary depending on your location and the nature of the issue. As a rough guide, we usually attend drainage emergencies within 90 minutes, or by appointment for non-emergencies.

What is a CCTV drain survey?

A CCTV drain survey involves using specialist camera equipment to inspect the inside of your drainage system. This allows our engineers to identify issues such as blockages, cracks, collapsed drains, root ingress, and pipe deterioration without unnecessary excavation.

CCTV surveys are often recommended for recurring drainage problems, property purchases, and suspected drain damage. Explore our CCTV Drainage Services for more information.

Can you repair collapsed drains?

Yes, we can identify and repair collapsed or damaged drains. Depending on the condition of the pipework, repairs may involve patch repairs, drain relining, or full pipe replacement. We will always assess the extent of the damage first and recommend the most suitable long-term solution.

Do you work with businesses as well as homes?

Yes, we provide commercial drainage services for a wide range of businesses, including offices, care homes, restaurants, landlords, retail premises, schools, industrial units, and property developers.

Can high-pressure jetting damage pipes?

When carried out correctly by experienced professionals, high-pressure water jetting is a safe and highly effective way to clear drains. Before jetting begins, we assess the condition of the drainage system to ensure the most appropriate method is used.

In cases where pipework is already severely damaged or deteriorated, we may recommend alternative solutions or repairs.

Do you provide preventative maintenance?

Yes, we offer preventative drainage maintenance services for both domestic and commercial properties. Regular maintenance, including drain cleaning, jetting, and inspections, can help reduce the risk of blockages, unpleasant odours, flooding, and costly emergency repairs in the future.

Do you offer drainage maintenance contracts?

Yes, we offer drainage maintenance contracts for both domestic and commercial customers, helping to reduce the risk of unexpected blockages in the future. Please contact us to learn more about what these contracts involve.

Can you provide drainage reports or documentation?

Yes, we can provide drainage reports and supporting documentation where required, including findings from CCTV drain surveys, maintenance visits, and drainage investigations.
