How we handle gutter sealing in Pentonville
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you are dealing with internal damp traced to a gutter joint and failed sealant on a garage door frame, we can put it right.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Pentonville, tell us how high the joints are and how to reach the back of the building.
We stand behind the work with a one-year guarantee.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Will sealant fix a dripping gutter joint?
In most cases, yes. If the gutter is sagging or cracked, sealing won’t last and we will say so.

Is sealing fascia joints something you do?
Yes. We seal open joints along fascias and soffits in a colour to suit.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.

Pentonville buildings and the weather
Historic houses like Dr Johnson's House (about 1.4 miles south) are a reminder that the area around Pentonville has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
If you let a flat or house near Essex Road station, leaking gutter joints on a rental are best caught before they stain the walls. Homes close to Church of Saint Peter include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Rest ladders on the wall, not the gutter
- Look for streaks or damp on the wall below gutters
- Get leaks sealed before the wet months
- Watch for drips in a downpour
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job while the frame is sound.

Related advice
What we’re called out for in Pentonville
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
People usually contact us when they notice one of these:
- Damp patches inside below a leaking gutter
- Gaps along fascia and soffit joints
- Water running down the wall below the gutter
- Cracked sealant along roofline trims
Pentonville is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
