Reviews

What contractors and developers say

Real references from the people who put us on their sites, from main contractors to long-standing clients.

  • Main contractor

    An outstanding subcontractor and a real asset to any company.

    We have had the pleasure of working with this subcontractor for over two years, and throughout that time they have consistently demonstrated an exceptional level of professionalism, reliability, and commitment. Their ability to prioritise urgent work while maintaining high standards has been invaluable to PTS. They work seamlessly with our team, communicate effectively, and take genuine pride in delivering quality results every time. It is rare to find someone with such dedication, consistency, and professionalism. We have no hesitation in recommending them. They are an outstanding subcontractor and a real asset to any company fortunate enough to work with them.

    Over 20 years, he has never let me down once.

    I have had the pleasure of knowing Davy for over 20 years and would highly recommend him. He has always turned up when required and never let me down once. Over the years we have had some challenging sites which Davy has managed to get over the line. I really appreciate his work ethic. I have had some very rural sites and, when it does not go to plan, Davy has stuck with it, sometimes not getting home until the early hours to get it done. Overall he is dedicated, professional and communicates well.

Questions

Frequently asked questions

The things site managers ask first. If yours is not here, call and ask.

How soon can you attend?

We are based in Ayr, so the west and central belt are quick to reach, often within a few days. Wider Scotland is booked in on programme. Call 07749 245626 with your site and the stage you are at, and we will tell you straight when we can be there.

How long does the work take?

A straightforward main can be swabbed, pressure tested and chlorinated in a single visit, with sampling to follow. The lab result then takes a few days. Timing depends on the pipe length and how many stages you need, so tell us the detail and we will give you a realistic window.

What happens if a sample fails?

The main is re-chlorinated, dechlorinated and flushed, then re-sampled, which costs days, not hours. We manage the disinfection and residual carefully the first time to get a first-time pass, because a failed sample is the thing that stalls a connection and holds up plots. We usually carry any re-chlorination and re-sampling at our own cost and time.

Do private mains need testing too?

Yes. Fire, sprinkler and rising mains, and any private supply that will carry water, need pressure testing. The water authority or Building Control will want a test certificate. We handle private mains the same way as adoptable ones. Chlorination and sampling will depend on the project.

How do you price a job?

On the actual scope, not a padded one. Send us the drawings or tell us the pipe size, length and which stages you need, and we quote only that. No work you can do without, no surprises on the invoice. Call or use the form and we will come back with a price.
