If you are experiencing problems with your gutter every time it rains and you are looking either to replace or repair it, this guttering replacement/repair guide will give your useful repair and maintenance advice.
House guttering is intended to protect your home from the many problems caused by damp and excess water. Gutters are an important part of your home because they collect rainwater and redirect it away from the roof and the sides of your house to the nearest drain.
Gutters can also channel rainwater into storage tanks – a useful water source for the garden without taxing your primary water supply, among other uses. It is when gutters become blocked with leaves or other rubbish that they need to be cleaned. A gutter that is left blocked may become damaged, causing further problems and the cost of repairing it.

Advantages and disadvantages of gutter guard
- Installing gutter guards can prevent gutters from clogging with leaves, water, and debris.
- Gutter guards can also decrease the frequency of gutter cleaning and prevent stagnant water from pooling in your gutters.
- Several heating gutters are available in the market to heat small areas and even the entire gutter run.
- Gutter guards some times more expensive than hiring a gutter cleaning company.
- Not all gutter guards on the market are equally effective, so you need to research before purchasing.
Gutter maintenance advice
- Regular gutter maintenance can prevent or delay repair or replacement in the future and save money.
- You should regularly check that your guttering is clear from blockages, particularly during winter or months with heavy rainfall.
- This is particularly important if your house is surrounded by trees that will drop dead foliage into the gutter, quickly blocking it.
- It is recommended that you clear and clean your gutters twice a year, or even more regularly if trees or plants are overhanging your roof that could cause leaves to build up in your gutters more quickly.
Blocked gutters
Poorly maintained guttering can wreak havoc with a building.
- When a gutter is blocked, it can cause water to pool at the bottom of the house, saturating the soil and leading to rising damp problems.
- Rising damp, whereby moisture moves up through the bricks, floors, and walls of your home, can cause significant damage to the structure of your property.
- Water may also pool near the roof, which causes problems with penetrating damp.
- Blocked gutters also can result in water running down the side of the house, causing moss and mold growth on the exterior of the building.
- Moss or grass growing in the gutter will also need to be removed to ensure the guttering is working efficiently.
- If water is flowing freely from the down-pipe and into the drain, then there is a good chance your guttering is working.
- Check the remainder of the guttering for leaks – joints between pieces of guttering must be securely fastened and tight.
- Metal guttering needs to be repainted roughly every five years to prevent rusting, which you may find unsightly.
- In one-and two-story buildings, the gutters can be accessed with a ladder and sometimes with scaffolding.
- Debris can be removed from the gutters by using a trowel – but wear gardening gloves to prevent blisters and splinters or another injury.
Gutter cleaning cost
If your gutters are two or more stories high, you should hire professionals to do the cleaning and maintenance, as the risk of injury at those heights is great.
The average gutter cleaning cost per m2 is £5 – £8 per m2, but there might be an extra charge for unusually shaped roofs or external features.
The average cost of cleaning gutters is: £150
Gutter Repair & Maintenance Advice
Fixing minor problems as they arise will be more cost-effective than undergoing a major repair at a later stage.
It is possible to patch up minor leaks with gutter sealant, but such patches seldom last very long. If there are many of these little leaks throughout the guttering, it’s best to replace the gutters.
Sagging: If your gutters are sagging, extra supports should be added so that the entire length is fully supported and fits flush to the walls. These supports are usually attached to the fascia boards, and if the fascia is rotted, broken, or uneven, that may need to be replaced.
Slope: Guttering needs to have a constant 1:40 slope to the outlet to ensure proper drainage. Sometimes support brackets may have to be adjusted to ensure that this requirement is met.
Guttering Materials: Guttering is manufactured from many different materials, such as cast iron, PVCu, aluminum, lead, zinc, steel (galvanized or painted), copper, and more. The material from which your gutters are made will determine the best methods for repair and influence the cost of such repairs.
PVCu guttering: This type of guttering tends to develop leaks at the joints due to the perishing of the rubberized gaskets used to join the lengths. It is also susceptible to damage from ladders leaned against it and to warping and sagging caused by insufficient support or broken gutter brackets.
In addition, period homes might already be fitted with older metal guttering that should be matched when being repaired or replaced. PVCu is the most commonly used material for guttering today. Unlike the metal guttering used in the past, PVCu guttering will not rust or corrode. It’s also lighter and cheaper than the older metal gutters.
Aesthetics: Many conservation officers recommend cast iron or cast aluminum guttering (pdf), which is in keeping with the period fittings of older houses. Cast aluminum is lighter than cast iron and more resistant to corrosion while still being very similar in appearance. For a more modern house, extruded aluminum, zinc, or stainless steel are also viable options.
Downpipes: If you have cleared your gutters of all leaves and debris and repaired other defects but find that your gutters are still leaking, it may be necessary to install new downpipes. In terraced houses, there is often an insufficient number of downpipes to start with. The ideal number of downpipes is one per three small terraced houses, although one per two is better.

How to know if you need new gutters?
- If there are several problems with your gutters, or the damage sustained is too substantial for repairs, replacing portions or perhaps even all your guttering will become necessary.
- The first consideration is once again the material that your gutters are made from. The cost implications of gutter replacement depend largely on this factor.
- There are also design and architectural differences in how PVCu and cast iron (for example) gutters are attached to the house and how they integrate with the downpipes.
- If you want to replace your cast iron guttering with PVCu guttering, it will also be necessary to replace the downpipes as well.
- When replacing the guttering on terraced houses, the guttering will be matched and married to the guttering of the houses on either side, and the correct adaptor must be used for this purpose so that there are no leaks.
- If you are only going to replace one section of guttering, it should be possible to find guttering that matches the existing gutters. Still, it would help double-check the profile and diameter to make sure that it is an exact match.
Gutter replacement cost
The average cost of replacing an old gutter with a new one in the UK ranges from £480 to £720. The cost of replacing guttering depends on the material you choose, the condition of the fascias, how accessible the roofline is, and the type of property you live in.
On average, the cost of replacing or refitting a gutter comes around to £32 per linear meter. For cast iron gutters, the cost increases to approximately £57 per meter. PVCu gutter replacement starts from £35 per meter, and downpipe replacement with a new cast iron pipe costs £75 per meter. Expect to pay 20% – 30% more if you live in London as living costs are higher there.
The table below outlines the estimated average costs for common repairs and gutter replacement. For example, replacing all the gutters on a semi-detached house where the gutters are easily accessible would cost about £550 for a 20-meter gutter. Adding extra down-pipes would cost an extra £100 per pipe.
Guttering replacement costs per meter (price estimates)
| Works | Labour and material cost (including VAT) |
|---|---|
| Supply and fit of a leaf guard to an existing gutter | £25 – £30/m |
| Replacing a gutter support bracket | £18 -£20/m |
| Taking off and refixing an existing PVCu gutter | £35 – £50/m |
| Taking off and refixing an existing cast iron gutter | £57 – 60 /m |
| Supply and fix stop end to PVCu gutter | £15 – £20/m |
| Gutter realignment | £15 – £25/m |
| Takedown existing and replace with new PVCu gutter (including all fixings) | £35 – 40/m |
| Takedown existing and replace with new cast iron gutter (including all fixings) | £70 – 75/m |
| Takedown a downpipe and replace it with a new PVCu pipe (including all fixings) | £35 – 40/m |
| Takedown a downpipe and replace it with a new cast iron pipe (including all fixings) | £75 – 80/m |
Roofers normally carry out roof gutter repair and roof gutter replacement. They are experienced and equipped to work at roof height and integrate guttering into the roof structure. Different contractors are likely to charge differently, so it is recommended that you shop around for the best quote.
Several companies offer multiple services, such as fascia and eave overhauls in addition to guttering replacement. Don’t let cost be the determining factor! Choosing an experienced contractor with a proven track record could save you from redoing a shoddy or incomplete job done by the company with the cheapest quote.

Down-pipe Maintenance and Repair
Sometimes the leaks or other problems are not in the guttering itself but rather in the downpipes. These could become dislodged or cracked or have sprung a leak at a joint. Downpipes are also susceptible to blockages. If a sudden temperature drop occurs, the water frozen inside the pipe is likely to split the pipe and, after thawing, will spill water onto the supporting wall.
If there is a blockage in the pipe, pushing along, stiff pole down the pipe should dislodge it. Before doing so, cover up the drain below the pipe so that the debris cannot enter the drainage system.
Who must replace damaged pipes? PVCu pipes are joined by brackets every 1.8m, so removing a section and replacing it is fairly straightforward. However, old cast iron pipes were fitted to walls by long metals spikes, and removing these can cause serious damage to your brickwork.

When you dig deeper, it becomes clear that the cost of guttering depends on the type of material you decide to use. In case you are up for UPVC, which remains a very well-embraced option for guttering due to the low cost and simple installation process, you should be pretty fine.
If you want a lightweight, long-lasting metal that is not prone to rust, Aluminium is your best choice by far. However, if it comes down to robustness, nothing can beat the option of steel. It is a fact that steel guttering costs more than other types. However, the maintenance cost is low if you go with this option. The following data should represent the costs clearly:
Example prices for gutters
The estimated cost of UPVC-type guttering: A half-round gutter with dimensions 52 x 112 x 4000mm will cost around £8.99 if you buy it from HomeBase. In that same store, rainwater pipe having a size of 2.9cm x 2m will cost you £8.49
The estimated cost of aluminum-type guttering: If the aluminum gutter is the option, the price will come to be about £27.99 for the Victorian Ogee variety having dimensions of 102mm x 54mm x 1.83m. If you go for the 102mm x 76mm x, 1.83m dimensioned Ogee. Instead, the amount you are required to pay is £41. The costs given are based on the popular online store called GMD Pennine
The estimated cost of steel-type guttering: From the online store Rainwater Products, purchasing a gutter made of cast iron with a length of 115mm will cost £27 on your part, whereas, for a steel variety of 125mm, you will need to spend £19.50
If you decide to get a professional for performing the installation process, you should collect at least 3 different quotes before settling on one. In addition, make sure that the professional you work with is insured as well as trusted.
Dealing with Damp
Even after the guttering has been repaired or replaced, there is still the aftermath of the damage caused by leaking or overflowing gutters. The first sign of damp is a musty smell, followed by damp patches on the walls, evidenced by staining, peeling, and bubbling paint or wallpaper.
Damp proofing
Damp proofing can be achieved by the application of a paint-on damp proofing product. This can protect your walls and floors and prevent damage to wood and timber in the home. However, this can also negatively affect the breathability of the surfaces, preventing the existing damp from evaporating or drying out. Using lime-based plaster and concrete will allow for better evaporation. In severe cases, the damaged plaster will have to be chipped out, sanded down, and replaced using a lime-based plaster to maximize breathability.
It is also necessary to deal with surface runoff and prevent water pooling around the base of your house and exacerbating the damp problem within. This surface water can erode and undermine your foundations, which makes removing them vital.
So that this water is not added to the wastewater and overwhelming the sewage drainage systems. It is necessary to channel it into a soakaway situated at least 5m away from the house. Underground pipes carry the water into a pit measuring 1m x 1m x 1.2m, filled with hardcore, and topped 50mm of concrete on a polythene sheet and a 25mm layer of sand blinding. Setting up this soakaway will cost you about £250.
Preventing damp in basements
In basements, the earth around the walls allows moisture to come into direct contact with the structure, and this can cause serious damp problems. One way to deal with this is the aforementioned waterproof coating. However, this does not remove the damp – it simply prevents it from coming inside. who can also install a membrane system to allow drainage.
This system relies on installing a studded membrane between the wall and the wall covering, creating a gap that will allow water to run down to the floor, which is also fitted with the same membrane, and into a drainage system. Often a sump pump is required to handle the drainage of this water.
Damp solutions for basements depend on the specific construction of the structure and its intended purpose. If a contractor is hired to solve the problem, they should advise you on the best method for dealing with your particular situation.
