Gutter sealing in The Folly
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame using a sealant made for outdoor use. We work on soffit joints, gutter end caps and roofline trims, and common reasons people get in touch are open joints in fascias and soffits and internal damp traced to a gutter joint.
Around The Folly, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Whatever the size of the job, it’s backed by our 12-month guarantee.

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, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Surface by surface
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Gutter end caps
Stop ends hold back water at the end of a run. A failed seal makes them leak.
What affects the cost of gutter sealing
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- The old material and how stubborn it is
- Whether the work is at height
- How many rooms, windows or areas are involved
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Your questions about gutter sealing in The Folly
I let a flat near Harpenden station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is The Folly within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. Each joint is cleaned and sealed.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long will you be here?
Typically it takes a few hours, depending on the number of joints and the access. Larger jobs naturally take longer.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Outside joints around The Folly
With historic houses such as Shaw's Corner (about 2 miles north-east) nearby, there’s older building stock in the area around The Folly as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you look after a building such as St Helen's Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St Helen's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens if it’s left?

Instead of a standard rate, 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 you get with us
- White, clear, grey or another colour, product permitting
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet
- Trusted Arbo and Everbuild sealants
