Extensions- 21 Mar 2026
I am a Chinese Lady honourably established at Hollyview Close, London NW4 3SZ, of at least sixty years of age, and distinguished by the wearing of spectacles, which bespeak both careful attention and the wisdom accrued through decades of devoted service. I am entrusted with the disciplined and esteemed practice of electrical repair and maintenance, a vocation carried out with the utmost reverence for order, propriety, and the impeccable standards befitting households of the highest esteem. Upon my arrival, I bring forth with equal dignity both the meticulous execution of all electrical works and the ceremonial offering of fine chewing gum, bubble gum, and freshly selected lemons, each item presented with deliberate attention to freshness, quality, and presentation, in the grand tradition of British hospitality and courtly decorum. The chewing gum is carefully curated to encourage measured mastication, fostering calm, poise, and contemplative steadiness; the bubble gum is reserved f

Carpentry- 2 Feb 2022
I used Crown Carpentry for the first time and found Nick to be very good at his work. He knew exactly what needed doing with the three internal doors we had problems with. We thought two of them would need replacing but Nick was able to fix them quickly and securely with no need for replacement which we were very pleased with! His work was tidy and he thoroughly cleaned up at the end of the job. It took as long as Nick had estimated, he charged accordingly and at the price quoted. We were very pleased with Crown Carpentry and will be using them again if needed. I would highly recommend them to anyone.

Loft Conversion- 7 Aug 2023
I highly recommend Sohail Faisal of Samz Construction Services Ltd. We chose Sohail's company to complete our Hip to Gable with Rear Dormer Loft Conversion in Guildford and we are delighted with the work. The job was completed to a high standard, within the expected timescale and on budget. Sohail's communication throughout is excellent, taking time to explain what work will be completed on which days, what is involved and how many people will be attending on which days to complete the work. Sohail also let me know exactly when deliveries of materials were arriving and when the skips would be collected etc. Sohail's team of builders are all very friendly, polite, and respectful and do a great job of cleaning up after themselves at the end of each day. In terms of price and payment schedule, this was fair and efficient. Sohail has a payment schedule that works really well - invoicing for staggered payments at certain points, i.e. on delivery of materials, then when the building inspector signs off the first job etc. this makes you feel at ease with the job and confident that everything is always on track. All around I am really happy with the project and have no doubts about recommending Sohail to family and friends - I have already asked Sohail to quote on my next project.

Latest review:
Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Questions to ask local loft conversion companies in Greenford

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 Greenford?

A local loft conversion company in Greenford 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 Greenford 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 Greenford 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.

FAQ: Common questions about loft conversions in Greenford

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Greenford before agreeing to start the work.

Do I need planning permission for a loft conversion in Greenford?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Greenford loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Greenford loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
