Gutter sealing in Long Marston
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. Common call-outs are for damp patches inside below a leaking gutter and garage door frames letting rain in, across roofline trims, garage door frames and soffit joints.
Outside joints can only be sealed when they’re dry, so work in Long Marston is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our 12-month guarantee in Long Marston and across Hertfordshire.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a few hours. For a village or hamlet like Long Marston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Tell us if parking is tricky

Long Marston buildings and the weather
With historic houses such as Ascott House (about 4.3 miles north) nearby, there’s older building stock in the area around Long Marston as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Long Marston VA Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Cheddington station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

- Old sealant on roofline trims that has split
- Garage door frames letting rain in

Questions from Long Marston
Do you cover Long Marston for gutter sealing?
Yes, Long Marston is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
I let a flat near Cheddington station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is sealant enough for a gutter that has dropped?
No. If the gutter sags, the joints keep opening, so the brackets need fixing first.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
How long does the job take?
Typically it takes anything from an hour or two to a few hours. Larger jobs naturally take longer, and we will say how long yours will take.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Why act early in Long Marston
You don’t need new fascias just because the joints have opened. A neat seal closes the gaps as long as the boards are in good condition. Where a wall is exposed, as many are in small places like Long Marston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
