Complete Gutter Replacement
Old gutters past repair? We strip and replace the full system — properly sized, correctly graded.
- UPVC, aluminium & cast iron systems supplied and fitted
- Correctly calculated fall, capacity and outlets
- Full system — gutters, downpipes, fascia brackets and fittings
When Repairs No Longer Make Sense
Gutters that are cracked in multiple places, badly sagging, or over 20 years old are usually beyond economic repair. Patching one section only shifts the stress to the next weak point, and before long you are paying for repair after repair on a system that is fundamentally worn out.
Radiant Roofing carries out full gutter replacements in UPVC, aluminium and cast iron. We strip the old system, check the fascia boards for rot, and install new gutters and downpipes that are properly sized and graded for your roof area — giving you decades of trouble-free drainage.

Frequently Asked Questions
A full UPVC gutter replacement for a semi-detached property typically costs between £600 and £900. Aluminium systems are more expensive, usually £1,200 to £1,800, while cast iron can range from £1,500 to £2,500 depending on the profile and property size.

Most residential gutter replacements are completed in one to two days. Larger properties or cast iron systems may take a day longer. We will confirm the expected duration in your quote so you can plan ahead.
UPVC is the most popular choice — it is affordable, lightweight and virtually maintenance-free. Aluminium suits modern or coastal properties where corrosion resistance matters. Cast iron is ideal for period homes, listed buildings and conservation areas. We will recommend the best option based on your property style and budget.
We cover Kent, East Sussex, West Sussex and Surrey. Our teams regularly carry out gutter replacements in Tunbridge Wells, Crowborough, Sevenoaks, Tonbridge, Uckfield, Haywards Heath, East Grinstead and the surrounding towns and villages.
Yes. All gutter replacements are backed by our workmanship guarantee. Materials carry their own manufacturer warranties — typically 10 years for UPVC, 25 years for aluminium, and longer for cast iron. If anything goes wrong with our installation, we put it right at no extra cost.
