Walstead Gutter Sealing
Problem with your gutter and fascia joints in Walstead? We cut out the old, prepare the joints and apply the right sealant.
- Wet patches on the wall under a gutter joint
- Gaps along fascia and soffit joints
- Water dripping where gutter sections meet
Gutter sealing in Walstead
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where one is available. Common call-outs are for water running down the wall below the gutter and stop ends leaking at the end of a run, on garage door frames, soffit joints and gutter joints.
In a village or hamlet like Walstead, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why act early in Walstead
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Around Walstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What we are called out for in Walstead
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end.
Keep an eye out for these signs:
- End caps that drip every time it rains
- Water dripping where gutter sections meet
- Failed sealant on a garage door frame
- Earlier gutter repairs that have peeled off

What gutter sealing looks like in Walstead
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Ockenden Manor (about 3.2 miles west) nearby, there’s older building stock in the area around Walstead as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Walstead questions
Do you work for landlords with property near Haywards Heath station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do gutter sealing in Walstead?
Yes. Our work covers London and the South East, and Walstead is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
How long does gutter sealing take?
Most jobs take a few hours, depending on the number of joints and the access. Your quote will say how long we expect yours to take.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
