Commercial box-gutter repairs and waterproof lining across Sussex
Commercial box-gutter repairs and reinforced lining across Sussex. Outlet, joint and upstand investigation with planned access and written scopes.
A clear diagnosis first
A practical approach to commercial box gutter repair in Sussex
A commercial box gutter is a drainage channel and a waterproof roof detail at the same time. Failure can interrupt a business long before the external defect appears dramatic: water may track beneath roof sheets, enter insulation or discharge inside at laps, outlets and movement points.
Bespoke Sussex Roofing surveys box gutters on industrial, retail, workshop and managed-property roofs across East and West Sussex. We record the substrate, existing lining, falls, joints, outlets, penetrations and access constraints before recommending a local repair, reinforced liquid lining or more extensive renewal.
The work
Commercial gutter defects investigated systematically
Outlets and sumps
Restricted, poorly positioned or defective outlets can hold water against laps and upstands; capacity and maintenance access are considered.
Joints and movement
Long gutters move with temperature. Splits often develop at rigid repairs, laps, changes of direction and unsupported sections.
Upstands and roof-sheet junctions
The lining must terminate securely beneath or against the adjoining roof construction without creating a route behind the system.
Reinforced liquid lining
Where compatible, a prepared and reinforced liquid system can create continuous waterproofing around complex shapes and local details.
Local considerations
A repair plan that respects business operations
Commercial work often requires agreed access times, protection beneath the work area and coordination with tenants or site managers. Our written quotation identifies known access and preparation requirements and can separate urgent containment from the planned permanent repair.
Across Sussex, local contact routes include Brighton 01273 447495, Worthing and coastal West Sussex 01903 958694, Horsham 01403 915855, Mid Sussex 01444 810086 and Pulborough/Storrington 01798 879385. Email photographs, plans or previous repair information to help us assess the enquiry.
The actual repair depends on substrate condition, movement, falls, outlet capacity and how the lining can terminate beneath adjoining roof sheets.

Sussex roofing FAQs
What causes commercial box gutters to leak?
Common causes include split laps, failed previous coatings, movement, blocked or inadequate outlets, defective upstands and corrosion or deterioration of the substrate.
Can a box gutter be relined without removing the roof sheets?
Sometimes, depending on access to the upstands, substrate condition and the required termination. The survey determines whether a continuous compatible detail can be achieved.
Do you work around business opening hours?
Access and work times can be discussed during quotation. Any out-of-hours requirement must be specifically agreed rather than assumed.
Can you provide temporary leak containment?
Where safe and appropriate, temporary measures may be possible. They are identified as temporary and do not replace a properly specified permanent repair.
Is commercial gutter lining guaranteed?
Qualifying work receives the written guarantee stated in the quotation. Coverage depends on the agreed preparation, substrate and lining scope.
