Our Most Requested System
Aluminium guttering, installed and replaced.
Aluminium is the system we fit most often, and for good reason. It is the sensible upgrade for a normal family home tired of sagging, leaking plastic gutters, and it is equally at home on an extension, a new build or a Cotswold stone cottage.
We install seamless aluminium rolled on site, extruded and cast aluminium ranges, and cast-iron-effect profiles, all powder coated in the full RAL colour range. Specialist quality, on everyday premium homes.

Why homeowners choose aluminium
30+ year lifespan
Aluminium does not rot, rust or go brittle. Properly installed, it outlasts several plastic systems.
Almost no maintenance
A powder-coated finish is washed, not repainted. No scraping, no priming, no ladders every few years.
Clean contemporary line
Crisp profiles and concealed fixings give a sharper eaves line than moulded plastic.
Full RAL powder coating
Any colour, matt or satin, matched to windows, doors, fascias or existing rainwater goods.
Stronger than plastic
Rigid sections hold their shape across long runs and take the weight of snow, ladders and debris.
Traditional or modern
Half-round, ogee, box and cast-iron-effect profiles cover cottages through to contemporary architecture.
Ideal for extensions
Match the new roof to the rest of the house, or upgrade the whole property in one visit.
Whole-house replacement
Gutters, downpipes, fascias, soffits and copings renewed together as one coordinated job.
Replacing plastic guttering with aluminium
Most plastic systems fitted in the 1990s and 2000s are now at the end of their life. The symptoms are familiar: joints weeping onto the wall below, gutters sagging between brackets, brittle sections cracking when a ladder touches them, and green staining down the render or stone.
Patching rarely pays. Replacing the run in aluminium costs more on the day and removes the problem for a generation, usually including new brackets, outlets and downpipes so the whole system is hung to a correct, consistent fall.
We strip and dispose of the old system, check the fascia and timber behind it, repair or replace where needed, and install the new gutter with the correct bracket spacing for the roof area it serves.

Profiles, sizes and finishes
- Half-round, ogee, moulded and box profiles
- Seamless gutter rolled on site, no joints between stop ends
- Cast-iron-effect ranges for period and Cotswold stone homes
- Deep-flow and oversized sections for large roof areas
- Round, square and rectangular downpipes
- Matching aluminium fascias, soffits and copings
- Full RAL powder coat, matt or satin
Seamless aluminium guttering
Seamless aluminium guttering is rolled on site, on the day, from a continuous coil. The machine forms the profile to the exact measured length of each elevation, so a forty foot frontage is one single piece of gutter with nothing between the two stop ends.
Every joint in a gutter is a future leak. Sectional plastic systems rely on rubber seals that harden and shrink, which is why the staining on a wall almost always starts directly under a union. Removing the joints removes the failure point, and it gives an unbroken shadow line along the eaves that looks markedly cleaner on a long modern elevation.
Outlets, internal and external angles and stop ends are formed and sealed as part of the run. Seamless suits straight, uninterrupted elevations best; on a heavily broken roofline with many returns, an extruded or cast aluminium system can be the better answer, and we will say so.
Powder coated aluminium guttering
All of our aluminium is finished in polyester powder coat. The coating is applied electrostatically to a cleaned and pre-treated section, then baked on, so it bonds to the metal rather than sitting on top of it like paint. It does not flake, blister or need repainting, and the colour holds against UV far longer than a moulded plastic gutter will.
The full RAL range is available, matt, satin or gloss. The most requested finishes locally are heritage black on Cotswold stone and rendered cottages, anthracite grey RAL 7016 on new builds and extensions to match modern windows, and a colour matched to existing fascias or joinery where only part of a property is being renewed.
Coastal and exposed sites can take a marine grade coating specification. On listed buildings and in conservation areas we will agree the profile and finish with the conservation officer before anything is ordered.
In summary
- Best suited to
- Family homes replacing tired plastic guttering, extensions, new builds, barn conversions, and period properties wanting a cast iron appearance without the weight.
- Typical investment
- Around £5,000 to £10,000 for a whole-house aluminium replacement on a typical family home, depending on size, storeys and access. Smaller extension runs cost considerably less.
- Areas covered
- The Cotswolds, Oxfordshire, Gloucestershire, Wiltshire and Berkshire, including Oxford, Witney, Woodstock, Burford, Chipping Norton, Cirencester, Cheltenham, Tetbury, Marlborough and Swindon.

Aluminium Guttering
Questions we are asked most.
How much does aluminium guttering cost to install?+
Most whole-house aluminium gutter replacements on a typical family home fall between around £5,000 and £10,000, depending on the length of gutter run, the number of storeys, access, and whether downpipes, fascias and soffits are renewed at the same time. Send photographs and a postcode and we will give you an indication before visiting.
Is aluminium guttering better than plastic?+
Yes, for almost every property. Aluminium does not become brittle in UV light, does not sag between brackets in hot weather, holds its colour, and is typically expected to last 30 years or more against roughly 10 to 15 for a plastic system. It costs more initially and is usually the last gutter a house needs.
What is seamless aluminium guttering?+
Seamless gutter is rolled on site from a coil to the exact length of each elevation, so there are no joints between the stop ends. Fewer joints means fewer places for a leak to start, and a cleaner unbroken line along the eaves.
Is powder coated aluminium guttering worth the extra cost?+
Polyester powder coating is baked onto the aluminium rather than painted over it, so the colour does not flake, chalk or need repainting. It is washed down occasionally and left alone. Against repainting a plastic or iron system every few years, it pays for itself well inside the life of the gutter.
What colours are available?+
The full RAL range in polyester powder coat, including heritage black, anthracite grey, and colours matched to existing windows, fascias or rainwater goods. Matt and satin finishes are both available.
Do you fit aluminium guttering near me?+
We are based in Highworth near Swindon and work across Gloucestershire, Oxfordshire, Wiltshire and Berkshire, from Cheltenham, Cirencester, Stow-on-the-Wold and Tetbury through Oxford, Witney, Burford and Woodstock, to Marlborough, Chippenham, Devizes, Newbury and Hungerford. Send your postcode and we will confirm straight away.
Can aluminium guttering suit a period or Cotswold stone property?+
Yes. Cast-iron-effect and moulded ogee aluminium profiles are visually very close to traditional ironwork from ground level, at a fraction of the weight. On listed buildings the profile and finish should be agreed with the conservation officer, and we are happy to help with that.
Do you install aluminium guttering on extensions and new builds?+
Regularly. A new extension is the natural moment to upgrade the whole house to one consistent aluminium system rather than matching new plastic to old.
