House Extension Professionals in Welwyn, Hertfordshire

“Recommended by a friend of mine. We contracted them to build us the new kitchen extension and dormer loft conversion on our terraced house in Barnet. Me and the family are extremely happy with services we received at all times. Work was completed on time that we agreed and to a high standard. They are highly skilled and friendly we was just very much impressed with all the workmanship and the service received. Trustworthy construction company who me and my family recommended.”

“PMB Construction have done a fantastic job on the complete architectural refurbishment of our period house. The director took the time to understand our aims and concerns and worked closely with us with courtesy and intelligence to realise the design while keeping costs to the original budget. He was always calm and competent, happy to accommodate small changes where needed and spending the time required on site to get things right. He knew how to pick his team, they were all fast, competent and respectful with excellent office backup. We felt very lucky to have worked with PMB Construction and could not recommend them more..”

“We started work on our loft conversion in August 2020. We had an unexpected need for planning permission which no one had anticipated but this was handled quickly and efficiently by the office. The team was professional, tidy and swift, and always informed us of everything along the way! We are really enjoying our new space in the loft and are so happy that we decided to go ahead with this project and chose Herko Ltd. Thank you again!”

“Darius and his team did a great job of our bathroom refurbishment (removing a wall between two adjoining rooms and completely refurbishing the new room and fitting a new bathroom suite, tiling and decorating) - from first contact to finishing the job Darius was very professional and responsive and consulted with us throughout to ensure all of the details for the work were as we wanted them. Tom and the rest of the team completed the work to a high standard, and we are very pleased with the overall finish. Minor snagging works were completed very promptly and without any problems. The works started on time and were completed within the approximate timetable indicated. Darius, Tom and their colleagues were also very pleasant to deal with, and we will definitely use them for other work to our home in the future.”

“We had really great experience with CLL from start to finish. Huw did a great job during the sales and explained really well how our loft conversion will look (double bedroom and bathroom). What we found extremely useful was a clear overview and expert advice on the whole process and all the prerequisites needed for a smooth running of the project. Huw was really helpful and I felt he really focused on our needs as customers. Renatas and the building team did a fantastic job in making it all a reality and we absolutely love new space they’ve created for us! The work was really well coordinated, done to a high standard and ahead of the agreed schedule, all of which was very important to us. We felt CLL really listened and understood our requirements. Guys were always on time and cleaned up after themselves each day. They were very polite, courteous and worked extremely hard to get the job done. Even our neighbours complemented on how efficient, hard working and noise minimal the team were! We are extremely pleased with our new space and would definitely recommend CLL to anyone.”

“We were very impressed with the workmanship and professionalism we received from Buildify and the friendliness of everyone we had contact with. Albert at the start was very responsive and helpful and immediately made us feel in safe hands. Our first-fix team (Adam and Monica, supervised by Asvad) were amazing, they felt like part of the family and really made us feel like they wanted the best for us and worked hard to achieve it, giving us ideas and advice along the way. Our second-fix supervisor Jack was very approachable and worked with us to take our loft through to a completion that we were very happy with. We would ( and have) recommend Buildify to anyone considering a conversion.”

“Prior to work commencing on our loft extension and kitchen, my husband and I had a number of meetings with Mr Brygola concerning the anticipated work. It was clear from those meetings that Mr Brygola was an extremely knowledgeable and experience builder. He presented himself professional throughout. My husband and I were overjoyed with the results, the work has been completed to a very high standard. Mr Brygola is very thorough and takes pride in his work. His team of builders are a credit to him. They arrive early doors and do not finish until the day's work is complete. They are friendly, respectful and tidy.”

“Best thing we ever did. Built to a very high standard and my new loft bedroom and bathroom is admired by all who visit. Thank you the Barnet Loft Company!!!”

“I have used Saspol many times over the last 8 years for jobs ranging from roof repairs to installing a completely new bathroom. Most recently used for chimney rebuilding and roof repairs. I have always found them to be reliable, courteous and honest. I have always been satisfied with the high quality of their work, as have the many friends and neighbours who have used them on my recommendation.”

“Eugene and his team did a fantastic job expertly and efficiently, transforming our loft space with great attention to detail. Communication was great, and they went the extra mile to satisfy our requirements. Wonderful team, highly recommended!”
