Platt Gutter Sealing
Gutter sealing across Platt and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- End caps that drip every time it rains
- Cracked sealant along roofline trims
- Rain getting in around a garage door
Gutter sealing in Platt
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s joint work rather than new guttering. We’re often asked to deal with open joints in fascias and soffits and old gutter sealant that has let go, across uPVC fascias, gutter joints and garage door frames.
In a village or hamlet like Platt, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our 12-month guarantee in Platt and across Kent.

Outside joints around Platt
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Old Soar Manor (about 1.9 miles south) are a reminder that the area around Platt has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Platt Church of England Voluntary Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours, depending on the number of joints and the access, depending on the amount of work. In a small place like Platt, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- For business premises, tell us about site rules or sign-in

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Problems with the roof covering
- Gutters that have dropped or pulled away
- Guttering that needs replacing
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal

Signs you need gutter sealing in Platt
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
Most people get in touch after spotting one of these:
- Old gutter sealant that has let go
- Old sealant on roofline trims that has split
- Rain getting in around a garage door
- Leaking gutter joints and stop ends
Letting a property close to Borough Green & Wrotham station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Questions to ask before you book
- Whether you can choose the colour
- What guarantee comes with the work
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Clear leaves and moss from the gutters
- Do not leave a sagging gutter
- Do not lean ladders against the gutter itself
- Check the gutters during heavy rain
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
A leaking garage frame lets water reach stored items. A reseal sorts it.

What about gutters on a second or third storey?
Low gutters are simple to reach. If it’s higher up, let us know and we will confirm the access.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Leave it or put it right?
Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it has failed, we’ll tell you. In a small place like Platt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
