Very courteous and professional

Bernie was excellent, he listened patiently to my concerns, and then thoroughly checked the Bungalow for any leaks , he identified where the leak in the central heating pipes was, and also informed me that there was a 30% damp reading in the shower room , which was not connected to the central heating pipework , but he suspected it was a leak from the shower. He also gave me some very good advice re the pipework in the loft. He was very courteous and professional .

A fabulous service, quick and efficient

While I think it’s a fabulous service, quick and efficient, systematic and state of the art technology, £500 net of VAT would have been my ideal price! Very courteous and gave reasons for the process and any questions he asked. ..and was incredibly patient when the dogs were weaving around him while he was doing difficult work.

Rosemary Hill from Somerset

Best engineer who has visited my home. 

Chris arrived on time and worked very hard continuously for almost 6hrs 30mins, and never had a break. He was courteous, informative, knowledgeable, pleasant, obeyed the covid restrictions fully whilst in my property and was helpful whenever i asked a question. Chris was possibly the best engineer who has visited my home.

Very adept at finding the source

I am a resident of the Print House in London. We have had several leaks in our building since it was renovated and made part residential in 2012. Our managing agents, Lamberts, organised a visit today which Barry attended. It is the second time he has attended site to locate the source of leaks. He is professional and very adept at finding the source – something others have not done on both occasions he was here.

I cannot rate his work and this company highly enough.

An unexplained water leak led to contacting my insurance company who appointed LDS to inspect the problem. I expected a quick half-our visit but three-and-a-half hours later Adrian was still working on sourcing the problem. It was great to see such a professional job carried out particularly given the Covid circumstances. I cannot rate his work and this company highly enough. Would definitely recommend.

Joyce Quarrie from London

Efficient and friendly

Your engineer Russell was able to tell us more about our central heating system than British Gas engineers! Russell was efficient and friendly and had British Gas done their job properly with the leak sealer as Russell did when he drained down the CH system then I would probably not have needed the leak survey.

David Head from Farnham

Pinpointed the leak on 2 mains

Lds done exactly what they promised turned up on time and pinpointed the leak on 2 mains water within 1 half hours. Engineer stayed on site until excavated to ensure leak detection was accurate. On a 24 metre length of mains water detection was within 200 mm of leak saved me a lot of time and money as the location was on a private road that had just been topped out.

Daniel Swift from Warwickshire

Very impressed with his customer service

Please be advised of the following service that was provided by your team member, Mr Barry Cronin. I was very impressed with his customer service, knowledge, care and understanding of the problem we were faced with and how he kept us informed throughout his inspection work. It is so nice to see someone who can see the whole picture and not just the problem. An absolute pleasure and would recommend him highly.
