Fern: your questions answered
Can you do gutter sealing in Fern?
Yes, Fern is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Is Fern within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Will sealant fix a dripping gutter joint?
Often, yes. A clean, dry joint resealed with gutter sealant normally stops the drip. If the section is split or warped, it needs replacing.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you reach high gutters?
That depends on the building. Let us know the height and the ground below and we’ll confirm what’s needed.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How we handle gutter sealing in Fern
It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job while the gutter is still sound. Common call-outs are for drips from gutter joints and end caps and failed sealant on a garage door frame, on soffit joints, uPVC fascias and gutter end caps.
Around Fern, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
Whatever the size of the job, you get the same 12-month guarantee in Fern and across Buckinghamshire.

Different surfaces, different methods
Garage door frames
Frame-to-brick joints face the weather. An exterior sealant suits them.
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.
Gutter sealing in Fern: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cliveden (about 2.7 miles south-east) nearby, there’s older building stock in the area around Fern as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Little Marlow CofE School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Bourne End station? Then leaking gutter joints on a rental are best caught before they stain the walls.

Why act early in Fern
Sealant will not clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. Around Fern, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

How we quote for gutter sealing
There’s no set price list, because no two jobs are the same. What we look at:
- The number and length of the joints
- Access and height
- When we can work, for business premises
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
You do not need to know the technical terms. Just tell us:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- The problem you’ve noticed
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

When to call us in Fern
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Signs it’s time to call us include:
- Water running down the wall below the gutter
- End caps that drip every time it rains
- Damp on an inside wall under a dripping gutter
- Open joints in fascias and soffits
For an older house near a landmark such as Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What to look for in a quote
- How hidden problems are handled
- When the joint can take water or movement
- How the joint is cleaned and prepared
- Who turns up on the day
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes an hour or two for a few joints, longer for a full run. For a village or hamlet like Fern, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Clear items away from the joints we are working on
