How we handle gutter sealing in Stanmore
We don’t replace gutters, fascias or roofs. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. If you’re dealing with fascia boards with gaps between them and leaking gutter joints and stop ends, we can help, on garage door frames, soffit joints and gutter joints alike.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Stanmore, joints up high may need ladders or other access, which is worth talking through when you book.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why deal with it now?
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right compared with treating damp later. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Stanmore.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How the job changes by surface

Trim joints are cut out and resealed suited to the material.
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
Questions from Stanmore
I let a flat near Harrow & Wealdstone station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Stanmore for gutter sealing?
Yes, Stanmore is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you clean gutters?
We clear what’s around the joints we work on. A full clean of the gutters is not part of it.
How long will you be here?
As a guide, most jobs take a few hours, depending on the number of joints and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before any work starts.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Keeping the joints in good condition
Looking after new joints is easy:
- Keep downpipes clear
- Keep an eye out for wet patches below a joint
- Clean out the gutters once or twice a year
- Look at the gutters while it’s raining
Make sure downpipes are not blocked, so water can get away. Blockages push water back along the gutter.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from an hour or two to a few hours, depending on the size of the job. In Stanmore, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

What gutter sealing looks like in Stanmore
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
As a London address, Stanmore can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as Church of St John, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Harrow & Wealdstone station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
