Crofton Park Gutter Sealing
Gutter and fascia joints in Crofton Park need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Quick sealant fixes on gutters that didn’t last
- Old sealant on roofline trims that has split
- End caps that drip every time it rains
How we handle gutter sealing in Crofton Park
We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. Typical jobs include trim joints where the sealant has failed and rain getting in around a garage door, on garage door frames, soffit joints and roofline trims.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
We stand behind the work with a 12-month guarantee.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Crofton Park buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
For landlords with property near Crofton Park station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you look after a building such as Stillness Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why deal with it now?
Replacing fascias because of open joints is generally unnecessary. Sealing the joints tidies them up if the boards are sound. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Crofton Park, the repair is bigger than the sealant job would have been.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Surface by surface
Roofline trims
Trims along the roofline are often finished with sealant. When it splits, water can get behind.
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes anything from an hour or two to a few hours. In a London area like Crofton Park, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
Before we arrive
- Tell us about any water getting in
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Advice
Questions from Crofton Park
Can parking be tricky for a visit in Crofton Park?
Parking in Crofton Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is Crofton Park in your area for gutter sealing?
Yes. We work across London and the South East, and Crofton Park is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. Cleaning the whole run is a separate job.
How long does gutter sealing take?
It depends on the size of the job, but most jobs take a few hours, depending on the number of joints and the access. We will give you a better idea when we quote.
What we’re called out for in Crofton Park
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
The problems people generally mention when they call are:
- Water running down the wall below the gutter
- Old gutter sealant that has let go
- Old sealant on roofline trims that has split
- Dripping gutter ends
As a London address, Crofton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
