How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes an hour or two for a few joints, longer for a full run. In a small place like Startop's End, access is usually the main thing to plan. 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.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we’re there.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

About our gutter sealing in Startop's End
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. We work on roofline trims, uPVC fascias and garage door frames, and people most often call us about old gutter sealant that has let go and water running down the wall below the gutter.
Older homes in small places like Startop's End may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
Your job is guaranteed for a year, as with all our work.

Startop's End buildings and the weather
With historic houses such as Cholesbury Manor House (about 4.4 miles south) nearby, there’s older building stock in the area around Startop's End as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Tring station change hands often, and 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 All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Startop's End questions
Do you work for landlords with property near Tring station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Will you come out to Startop's End?
Yes. Startop's End is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What information do you need?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We will confirm the access for higher gutters before we book.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is it possible to stop a gutter joint dripping with sealant?
Often, yes. Cleaning, drying and resealing the joint usually works. A split or warped section needs replacing.
Why act early in Startop's End
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. Where a wall is exposed, as many are in small places like Startop's End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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. You’ll know the price before we begin.

What the job involves on each surface
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
Roofline trims
Sealing roofline trims is joint work only. A roofer deals with the roof itself.
What we’re called out for in Startop's End
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
These are the problems we’re asked about most:
- Fascia boards with gaps between them
- Streaks down the brickwork from a leaking joint
- Dripping gutter ends
- Quick sealant fixes on gutters that didn’t last
If you look after a building such as Marsworth Church of England Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
