Gutter sealing for homes and businesses in Longfield
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough if the gutter is not damaged. We work on roofline trims, uPVC fascias and soffit joints, and the jobs we see most are old gutter sealant that has let go and failed sealant on a garage door frame.
Somewhere as small as Longfield, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All our work is covered by our one-year guarantee, wherever you are in Kent.

Different surfaces, different methods
Gutter end caps
Stop ends hold back water at the end of a run. A failed seal makes them leak.
uPVC fascias
Open fascia joints look untidy and can let water in. A neat bead closes them up.

Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- How we’d reach the joints
- Where the job is, and your postcode
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. For a village or hamlet like Longfield, 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 start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant will not bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
Ask for a quote

Looking after it afterwards
After the cure time, these simple habits help:
- Check fascia and soffit joints for gaps
- Clean out the gutters once or twice a year
- Look at the gutters while it’s raining
- Keep an eye out for wet patches below a joint
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
Sealant will not clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. Where a wall is exposed, as many are in small places like Longfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Questions from Longfield
Can you help a landlord with a rental near Longfield station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Longfield?
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.
How long does gutter sealing take?
That depends on the amount of work, but as a guide it takes anything from an hour or two to a few hours. We’ll tell you when we quote.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. For anything higher, we will confirm what access is needed once we know more.
Will sealant fix a dripping gutter joint?
Most of the time. If the gutter is sagging or cracked, sealing will not last and we’ll say so.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Downpipes that are blocked or broken
- Sagging gutters or broken brackets
- Rotten or damaged fascia boards
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Gutter end caps
- Garage door frames
- uPVC fascias
- Soffit joints
- Gutter joints
- Roofline trims
What gutter sealing looks like in Longfield
With historic houses such as Cobham College (about 4 miles east) nearby, there’s older building stock in the area around Longfield as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For an older house near a landmark such as Church of Saint Mary Magdalene, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Longfield Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Longfield station? Then leaking gutter joints on a rental are best caught before they stain the walls.
