Loft Conversion- 24 Apr 2023
Finn and Aaron arrived promptly to start flooring my loft. Materials had all arrived on time too and the job was well planned. They worked very efficiently and quietly and “just got on with it”. The work they completed was to a high standard and I’m really pleased with the result. Very neat and tidy - they even hoovered up afterwards! The job was completed in one day, not two as original quoted. I was also very happy that they agreed to do an extra job for me with no notice!!

Latest review:
Dan simply was great - we'd got 12 solid core interior doors and their fixings - the whole house, replacing the original hollow core doors. Each door needed the works - hinge rebates cutting, door adjusting, lock etc. The result is excellent and Dan did the job calmly and efficiently - and kept the place tidy and clean despite having to cut every door in the house. A job well done and on schedule.

Questions to ask local loft conversion companies in New Milton

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 New Milton?

A local loft conversion company in New Milton 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 New Milton 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 New Milton 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.
