We took 4 quotes and this was the best value for money. All staff involved were exceptionally helpful, professional and friendly. I am delighted with the finished product and would highly recommend Tarmasters to anyone.

Mr Stuart Logan

Fully satisfied with project from start to finish, from initial contact to completion of the contract. Everything was completed with timed precision and a member of your team came back to site to inspect and verify we were happy with the works. Thank you!

Mr Alan Roberts

We are delighted with every aspect of work, from the surveying stage through to construction, completion, and the aftercare we received. I look forward to working with your team again.

Phil Marshall, Plymouth Academy Trust

Thank you very much for the good job which you have done for us in repairing the surrounds of the church and the car park, it looks great!

First, may I say how pleased the neighbours and I are with the resurfacing. May I also add how pleasant the workers were, unusual in the trade to have such helpful and hardworking staff!

The Highway Inspector and myself had a walk around Persimmon, Ivybridge this morning and are very happy with the quality of work done yesterday, could you pass this on to your men please.

Dave Wilton
Steve Hoskins Construction

Thank you very much to the team for a superb job. I’m sure we’ll see them again before too long!

Jamie Halse
Stover School

Just to say thank you for your efforts (and speed) on the Woodlands Park Site. Positive feedback from the park and all looks good in the photos I have seen!

Berkeley Parks

All the residents appear very pleased with the works carried out on the drive. Many thanks and take care in these strange times.

St Ronans Property Management Company Ltd

Just a little note to let you know, a job well done. The boys were brilliant, you’ve got a great team.

Bob Hussey

Thanks for all you hard work lining this up. I know that Ben had to put in a lot of work to satisfy the local planning authority's requirements, partly due to the location on a narrow busy commuter route. The rest of the team did a fantastic job - it looks great. Thank you very much for persevering with this job as I know it was not easy.

Jon Couch

Our drive is looking brilliant. It was great to have it completed yesterday, especially a week ahead of time. Thank you.

David Harding

Thank you very much for the works done, everyone is so pleased with it even passers-by. The workmen were a great bunch and a credit to your company. High recommend!


Thank you for your incredibly kind donation of the labour, materials, and machinery which were involved with tarmacking the back lane and helped towards the build of our new extension and access to our property. The extension was built to ensure that Frazer has all he needs as he battles with Late Infantile Battens Disease. The development of the extension has already proved invaluable. Thank you on behalf of Frazer and our family.
