His (Alister’s) attention to detail was great – both in the preparation and delivery of the project.

We approached Alister Gammaldi of Gamcon Developments because we had a plan for an extension and renovation of a 3 bedroom brick veneer house. Alister was punctual to his appointments and thorough in his examination of our plans. He provided advice on issues and drew up a specification document that accurately reflected our ideas.

His specification document and quote were clear and complete with all aspects of the job included, he took the time to go through the documents carefully and explained any entries that were technically unclear to us, variations were listed and items we had pre-purchased were noted.

His attention to detail was great - both in the preparation and delivery of the project.

The work was organised with great communication to us about what would happen when, we were kept informed about any change in daily start times, deliveries and new subcontractors coming to the property.

His team arrived promptly, they were tidy, organised and accommodated us living in the house until essential work meant we had to vacate for a few weeks. At the end of each day the work area was tidied and made safe, tools put away, the house was always locked and secured. Our dog was managed with friendliness and great care to avoid any escape or hurt, which was really important to us.

When any adjustment or amendment need to occur, communication was prompt, well discussed and swiftly incorporated. A few changes we made were included in a trouble-free fashion.

The project was fantastically managed, came in on budget, on time and was carried out in a manner which gave us confidence that the quality of work was exceptionally high. The result of this project is a wonderful home built to our specification; it was actually an enjoyable experience working with Alister and his team. We would definitely contact Alister again for any future projects.

We have no hesitation in recommending Gamcon Developments to others who want to build, extend or renovate.
