Why us

Why Grimsby homeowners choose Custom Home Improvements

Grimsby takes the wind straight off the Humber and the North Sea, and the older terraces and semis across the town feel every gust of it at the ridges, verges and valleys. That is where most leaks start. We have spent 20 years fixing them properly, with a fixed written price before we start.

1

Properly local, 20 years in the area

We live and work in the same towns we serve. We know the local housing stock and which jobs give trouble round here. No franchise, no subcontractors shipped in from elsewhere.

2

Fixed price before we start

Your written quote is the price you pay. We itemise every cost upfront. No "while we're here" extras, no surprise invoices when the job is done.

3

Same-day callback, every time

Call or fill in the form and someone rings you back the same day. We confirm a visit date on that first call. No chasing, no voicemail loops.

4

Fully insured, paperwork ready

Public liability and employer's liability insurance in place on every job. We can email certificates before work starts, so there's no chasing needed.

Founder and roofer

“I started Custom Home Improvements with one simple rule - if I wouldn't accept it on my own house, it doesn't go on yours. Most of our work today comes from word of mouth and second jobs from happy customers. That's how I know we're doing it right.”

FAQ

Common questions

How quickly can you come out?
For active emergencies we usually get someone out the same day or next morning. Standard quote visits are typically within 2-3 working days, scheduled at a time that suits you.
Is the quote really free? Will you pressure me to book?
Yes, completely free, with no hard sell. We give you a written quote and follow up once and that's it. Most of our customers compare a few quotes; we're happy to be one of them.
Are you insured?
Yes. We carry full public liability and employer's liability insurance. We're happy to email a copy of the certificate before any work starts. Just ask.
What's covered by the 20-year guarantee?
All workmanship, meaning if something goes wrong because of how we fitted it, we come back and put it right at no cost, for 20 years. Materials are covered separately by the manufacturer's warranty.
Do you work outside Grimsby?
Our core area is Grimsby, Cleethorpes, Immingham and surrounding villages. We can occasionally take jobs further afield, but it's best to call and check.
Do I need to pay anything up front?
For repairs, no. You pay on completion once you're happy. For larger jobs we ask for a materials deposit once the job is booked, then the balance on completion.
