About our gutter sealing in Newnham
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. If you are dealing with streaks down the brickwork from a leaking joint and gaps along fascia and soffit joints, we can put it right, whatever the surface.
Older homes in small places like Newnham may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep downpipes clear
- Clean out the gutters once or twice a year
- Deal with a drip before winter
- Look at the gutters while it’s raining
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards.
What happens if it’s left?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. Around Newnham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What affects the quote in Newnham
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- The amount of work
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
When you contact us, these details help:
- Photos by email, if that’s easy

- What’s wrong with the joints now

What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes an hour or two for a few joints, longer for a full run. Somewhere as small as Newnham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- We look along the gutter and clear debris around the joints.
Before we arrive
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common questions in Newnham
Is Newnham in your area for gutter sealing?
Yes, Newnham is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is Newnham within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you work on high-level gutters?
Low-level work is easiest. We’ll confirm the access for higher gutters once we know more.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What gutter sealing looks like in Newnham
With historic houses such as The Vyne (about 4.6 miles west) nearby, there’s older building stock in the area around Newnham as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Hook station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near Church of St. Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.
