How we handle gutter sealing in Mapesbury
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. If you are dealing with quick sealant fixes on gutters that didn’t last and dripping gutter ends, we can help, whatever the surface.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep ladders off the guttering
- Clean out the gutters once or twice a year
- Watch for drips in a downpour
- Check fascia and soffit joints for gaps
Leave the new sealant to cure as we advise and avoid disturbing it.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.

How long before the joint can be used?

Is sealant enough for a gutter that has dropped?

What gutter sealing looks like in Mapesbury
The South East is one of 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.
Rented homes near Wembley Stadium station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. As a London address, Mapesbury can be tricky for parking: let us know about parking bays, permits or a driveway.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It generally takes an hour or two for a few joints, longer for a full run. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

Advice
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
