Bricklaying- 10 Jun 2020
We hired Jamie to take out a window and install a door. He was very polite, gave a good quote and timescales etc. He understood exactly what we wanted, visited a few times before starting to ensure measurements were exact and that small details that we requested were agreed and clear. Before he started we asked him to quote for another job and he completed both within the timescales given, plus he was clear about what would happen on what day, and stuck to it. Nothing was too much trouble, he is very courteous, his workforce too. He's understanding, responsive to contact, and an excellent job done as well as being very clean and tidy. We are already looking to have him do the next works we need to get in the pipeline! We would not hesitate to recommend him.

Conversions - General- 17 Mar 2022
Brett and his very experienced father took on an awkward job removing a chimney breast, a wall separating a dining room and kitchen, an ugly pair of French windows, a rear door and a window. This required three steel beams, two of which were bolted together at right angles and three lintels. Due to different ceiling heights, getting the overall height of the beams was demanding but it was done well. They fitted a new replacement window and set of bi fold doors. The job was made more difficult by some poor quality brickwork on the rear wall which slowed progress due to extra work to rectify the problem. The electricians and plasterer they used were very good. They also planned and advised on materials for a patio and garden path. I will use them later on in the year for some more work on repointing and wall ties.

Questions to ask local loft conversion companies in Emsworth

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Emsworth?

A local loft conversion company in Emsworth will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Emsworth should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Emsworth loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.
