Commercial Gutter Refurbishment for Industrial and Commercial Buildings Across the UK

Leaking, corroded or blocked commercial gutters do not just look bad. They cause water ingress, damage to insulation, stock and internal finishes, and accelerate structural deterioration across the building. ProClad Coatings restore failing commercial gutter systems to full drainage performance without the cost or disruption of complete replacement.

Why Commercial Gutters Fail and What It Costs You

Commercial and industrial gutters handle significantly larger volumes of rainwater than domestic systems. On a warehouse, factory or distribution centre, a single gutter run can be hundreds of metres long, managing thousands of litres of rainwater every time it rains heavily.

When that system starts to fail, whether through corrosion, joint failure, blockage or deteriorating coatings, the consequences go well beyond a visible leak. Water ingress at eaves level is one of the most common causes of internal building damage in commercial properties. It affects insulation, triggers structural corrosion in roof sheets and steel, damages stock, creates health and safety hazards and in severe cases disrupts operations entirely.

The frustrating reality for most facilities managers and commercial property owners is that the damage caused by failing gutters nearly always costs more to fix than the gutter refurbishment itself would have. A small leak left unaddressed for a season becomes damp insulation, corroded steelwork and potential roof failure.

The earlier the gutters are assessed and treated, the lower the overall cost.

The ProClad Approach to Gutter Refurbishment

Signs Your Commercial Gutters Need Attention

Most commercial gutter problems are visible from ground level if you know what to look for. These are the warning signs.
  1. Water Overflowing During Rainfall Gutters that overflow during moderate rainfall are blocked, sagging or no longer have adequate capacity to handle the volume of water from the roof above.
  2. Visible Rust or Corrosion on Gutter Surfaces Surface rust and corrosion on metal box gutters, valley gutters or parapet gutters indicate coating failure. Once corrosion takes hold, it progresses quickly toward the gutter base and joints.
  3. Staining or Damp Patches on External Walls Vertical staining running down the external wall from eaves level is a clear indicator that water is escaping the gutter system and running down the building face.
  4. Leaking Joints or Seams Joints that were previously sealed with mastic or sealant degrade over time. Once a joint fails, water tracks along the inside of the gutter and exits at low points, often inside the building.
  5. Internal Damp, Staining or Water Marks If water is penetrating at eaves level and tracking into the building, you will see damp patches or staining on internal walls, ceilings or insulation below the affected area.
  6. Standing Water in Gutters Water pooling in gutters after rainfall indicates blocked outlets, incorrect fall or a gutter base that has deformed over time. Standing water accelerates corrosion and adds unnecessary load to the gutter structure.
  7. Visible Sagging or Deformation Sections of gutter that are visibly sagging, pulling away from the fascia or no longer running to the correct fall indicate structural failure of the gutter bracket system.

If you are seeing any of these signs, the problem will not resolve itself. It will progress until it causes damage that costs significantly more to put right than a timely gutter refurbishment would have.

What Our Commercial Gutter Refurbishment Service Covers

Gutter refurbishment is not just a clean and a coat of paint. It is a structured programme of cleaning, repair, lining and protective coating that restores the gutter system to a fully watertight, functional condition. Our service covers the following.
  • Gutter Cleaning and Clearance All debris, silt, moss, leaves and blockages are removed from the gutter system before any assessment or treatment work begins. Outlets and downpipes are checked and cleared.
  • Condition Assessment and Survey We carry out a detailed inspection of the gutter structure, joints, fixings, falls and drainage. We identify all areas of corrosion, joint failure, standing water and structural deformation and provide a written condition report.
  • Joint and Seam Repair Failed joints, cracked seams and areas of localised damage are repaired and resealed before any lining or coating is applied. Fixing points and brackets are checked and replaced where necessary.
  • Gutter Lining Where gutters have corroded sections or compromised waterproofing, a liquid-applied lining membrane is applied directly over the existing gutter surface. This creates a continuous, fully bonded waterproof barrier that eliminates joints and seams where traditional systems fail. Systems such as Plygene Gutterline are backed by manufacturer warranties of up to 25 years.
  • Protective Coating A UV-resistant protective topcoat is applied to the external gutter surfaces to restore appearance, prevent further corrosion and extend the life of the gutter system.
  • Downpipe and Outlet Check All downpipes and outlets are confirmed clear and flowing correctly on completion.

OUR PROCESS

How We Work on Commercial Gutter Projects

Step 1 — Free Site Survey

We visit your site, inspect the full gutter system and identify all areas requiring attention. You receive a written condition report and a clear, fixed-price quotation before any work is agreed.

Step 2 — Cleaning and Preparation

The full gutter run is cleaned and cleared. All loose coatings, silt, debris and failed sealants are removed. Joint repairs and bracket checks are carried out before any coating or lining work begins.

Step 3 — Repair and Lining

Failed joints and corroded sections are repaired. Where lining is specified, the liquid-applied membrane is applied in multiple coats to the prepared gutter surface, creating a seamless, fully bonded waterproof barrier.

Step 4 — Protective Topcoat

A UV-resistant protective coating is applied to external gutter surfaces to match the existing building colour and provide long-term protection against weathering and corrosion.

Step 5 — Final Check and Documentation

Outlets and downpipes are confirmed clear. A full inspection is carried out and you receive your completion certificate, guarantee documents and photographic report.

Gutter Refurbishment vs Full Gutter Replacement

For most commercial buildings where the gutter structure is still sound, refurbishment delivers the same outcome as full replacement at considerably lower cost and with far less disruption.

Full replacement becomes the right recommendation when the gutter structure itself is no longer sound, where multiple sections are severely corroded through, or where the existing system no longer has adequate capacity for the building. We will tell you honestly at survey which route is appropriate for your building. We do not refurbish gutters that cannot deliver a lasting result.

RESTORING BUILDINGS. PROTECTING ASSETS.

Every Industry. Every Building. One Commitment to Lasting Protection.

Commercial buildings across every sector face the same challenge. Years of weather exposure take their toll on roofs, cladding, gutters and external surfaces. We work with businesses across the following sectors to stop that deterioration before it becomes a costly structural problem.

Office Buildings and Business Parks

Parapet gutters, box gutters and eaves gutters on commercial office buildings where leaks cause damage to internal finishes and disrupt tenants.

Warehouses & Distribution Centres

Large-scale valley gutters, box gutters and parapet gutters managing high volumes of rainwater. We work in phases around continuous operations to avoid disrupting loading bays and internal activity.

Agricultural Buildings

Rural buildings with exposed metal gutter systems subject to high moisture levels and debris loading. Robust refurbishment programmes built for demanding environments.

Retail Parks

External gutter systems on retail frontages and business parks where appearance and watertightness both matter. Protective coatings matched to the building's existing colour scheme.

Manufacturing Facilities

We coordinate access around shift patterns and production schedules. All work is completed externally, so internal operations continue without interruption.

Industrial Estates

Full gutter refurbishment programmes across multiple units, restoring consistent drainage performance and appearance across the whole estate.

 What Makes ProClad Coatings Different

There is no shortage of painting contractors in the UK. The difference is that we specialise exclusively in commercial and industrial buildings. That focus means better results, better products and site teams who understand the demands of working on occupied commercial properties.

Specialist Commercial Focus

We work exclusively on commercial, industrial and agricultural buildings. Every gutter refurbishment project we take on is for a commercial property owner, facilities manager or commercial landlord.

Structured Refurbishment, Not a Quick Fix

We clean, repair, line and coat. The preparation and repair work is what determines whether a refurbishment lasts 20 years or fails within two seasons. We do not skip steps.

Proven Lining Systems

We use specialist gutter lining systems backed by manufacturer warranties of up to 25 years. You receive proper documentation, not just a contractor guarantee.

No Disruption to Operations

All work is carried out externally from roof level. Your building stays operational throughout. No internal access required.

Honest Assessment

If your gutters need replacement rather than refurbishment, we will tell you that at survey. We do not apply linings over structures that cannot support a lasting result.

Nationwide Coverage

Teams across England, Scotland and Wales covering commercial and industrial sites throughout mainland UK.

Full Documentation on Completion

Photographic completion report, product data sheets, guarantee certificate and schedule of works issued on every project.

Cladding Spray Painting — Frequently Asked Questions

If you manage a commercial property and are considering coating or refurbishment work, these are the questions we get asked most often. If your question is not here, call us or submit an enquiry and we will get back to you within one working day.
Will the work disrupt our business operations?

No. Cladding spray painting is external work and does not affect internal operations. Overspray is fully contained during application. Entrance areas, car parks and surrounding surfaces are masked and protected. We can also work outside standard hours where needed.
Can you match our existing cladding colour?

 Yes. We colour match to any RAL, BS or manufacturer-specific colour reference. If you want to retain your existing colour or switch to something new, we can accommodate both. Colour is confirmed before any work starts.
Do the panels need to be removed during the process?

Significantly cheaper. Cladding spraying costs around £25 to £35 per square metre for a professional spray job, depending on size and complexity. Full cladding replacement, on the other hand, can cost £80 to £120 per square metre and involves weeks of disruption, waste disposal and new materials. For most commercial buildings, spraying is the smarter option by a considerable marginNo. All work is completed on site with panels in place. There is no need to remove, dispose of or replace any cladding. This is one of the primary advantages of spray painting over replacement.
What types of cladding can you spray paint?

We can spray paint virtually all types of cladding including plastisol, steel, aluminium, UPVC and composite cladding systems. If you are unsure whether your cladding is suitable, our free site survey will confirm this before any work is agreed or quoted.
How much does cladding spray painting cost?

Cost depends on the size of the building, the condition of the panels and the access requirements. As a guide, cladding spraying typically costs £25 to £35 per square metre. Full cladding replacement costs £80 to £120 per square metre. We provide a fixed-price quotation after the site survey. No hidden charges.
How long does the project take?

Most cladding spray jobs are completed within one to three days for smaller buildings. Larger sites or those requiring more preparation work will take longer. You receive a full programme of works before we start so you know exactly what to expect.
Can you match our existing colour or brand colours?

Yes. You can select from a wide range of RAL colours, and custom colours are also available, making it easy to match your building's design or brand identity. If you have a specific brand colour requirement, share the RAL reference or colour code with us and we will match it exactly.
Can you treat cut edge corrosion at the same time?

Yes. In most cases we identify and treat cut edge corrosion as part of the same programme of works. If the corrosion is significant, we may recommend a dedicated cut edge corrosion treatment before the cladding respray is carried out.

Leaking Gutters Will Not Fix Themselves

Every season a failing gutter system goes untreated, the damage it causes grows. What starts as a corroded joint becomes damp insulation, damaged steelwork and eventually a far more expensive problem than a timely gutter refurbishment would have been.

Book a free site survey and we will assess the full gutter system, tell you exactly what needs to be done and give you a clear, fixed-price quotation.

No obligation. No pressure. Just a straight answer from a specialist.
