I had a great experience with this surveyor for my boundary survey. They were very prompt in responding, professional throughout the entire process, and easy to work with. They offered the best quote compared to several other companies and had a much shorter waiting time. The work was completed efficiently and to a high standard. I highly recommend their services.
Councils now allow owners to build right on the boundary line between properties. A concrete foundation was poured which encroached on an angle in front of our carport, in preparation for a house to be constructed right against and along our driveway. We needed urgent assistance before the builders built on the foundation to ensure the boundary line was in the correct position, given that the whole site of our neighbours’ was raised by 1.3m and some of the initial survey markers had been buried under the fill. I found Sawley Lock O’Callaghan through a Google search and rang and talked to Danny. Sometimes, you get strong vibes when talking on the phone from the very first contact what dealing with a company is going to be like. Danny wasn’t sure they could fit us in with our immediate need and given the jobs they were already committed to. He checked and rang back and they went the extra mile for us and fitted us in. Everything Sawley Lock O’Callaghan said they were going to do, they did. From turning up on time, their level of professionalism and delivering the report as promised on time, enabled us to quickly resolve the boundary issue and our neighbours could proceed with only a week and a half delay to their pre-Christmas rush to undertake building works. It is unfortunately rare to have exceptional professional high quality customer service these days. Thank you very much for helping us. A well-deserved 5* review from the Norris family.
After multiple developments and boundary identification headaches, we have dealt with a few different companies. Since choosing Sawley Lock it is an absolute pleasure to deal with these people. A can-do attitude, excellent and informed advice, polite and generally great to deal with. Cannot recommend them highly enough.
I recommend this great team to anyone who reads this review. I personally thank Sawley Lock O'Callaghan team, for making it possible to complete what felt like initially impossible. Your professional service, guidance, support, great communications and management skills, makes your business stand out as exceptional. Thank you kindly. Keep up the great work.
I sent off for about 10 quotes for our particular job and not only did Sawley Lock come in at the best price but their service was fantastic. All enquiries were responded to efficiently, both via Email and over the phone, the service was carried out in a timely and professional manner and I was kept up to date throughout the process and everyone I communicated with was friendly and thorough. Highly recommended!
