Why I do things differently for you
Climbing into the loft isn't always practical, and it's hard to know who to trust. So I make it easy to see exactly what you're paying for.
- I film every step I record your job from start to finish, so you can see exactly what was done without going up a ladder.
- Sent the way that suits you I'll send the video by WhatsApp, text message or email, to you, or to a family member if you'd like.
- Pay 72 hours later Nothing upfront. After the job is finished you have 72 hours to watch the video and have the work checked before you pay.
- Family always welcome Have someone with you at the survey, or talk the quote over with them first. There's never any pressure to decide on the day.
I will never ask for money upfront or on the doorstep. If anything isn't right, tell me within the 72 hours and I'll put it right before you pay. After that, you're still covered by my 10-year warranty and your full legal rights. If you agree the work in your home, you also have the legal right to cancel within 14 days.
Free on every loft survey: I'll draught-proof your loft hatch on the day, whether you go ahead or not, as long as nothing, such as a loft ladder, is attached to the hatch.
