Gutter sealing in Grange Mills
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter is broken or sagging, we will tell you. Typical jobs include water running down the wall below the gutter and open joints in fascias and soffits, on soffit joints, garage door frames and gutter joints.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Grange Mills, tell us how high the joints are and how to reach the back of the building.
Big or small, you get the same one-year guarantee in Grange Mills and across Greater London.

The process
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes a few hours, depending on the number of joints and the access, and we explain the cure time before we leave. In a London area like Grange Mills, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Leave it or put it right?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

Is Grange Mills in your area for gutter sealing?
Yes, Grange Mills is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is parking a problem for a job in Grange Mills?
Parking in Grange Mills, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What does gutter sealing cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Signs you need gutter sealing in Grange Mills
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
It’s worth asking for a quote if you see:
- Drips from gutter joints and end caps
- Stop ends leaking at the end of a run
- Garage door frames letting rain in
- Old sealant on roofline trims that has split
As a London address, Grange Mills can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How the joint is cleaned and prepared
- The length of the guarantee
- Are they insured?
- Which sealant they’ll use, and why
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Sort out a dripping joint early
- Check the gutters during heavy rain
- Check that water runs out of the downpipes
- Keep ladders off the guttering
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.
