Leave it or put it right?
A new garage door isn’t needed for a leaking frame. Sealing the frame usually stops it, if the frame itself is sound. 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 Dalston.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

How we handle gutter sealing in Dalston
Sealant only bonds to a clean, dry joint. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you’re dealing with internal damp traced to a gutter joint and old sealant on roofline trims that has split, we can help, whatever the surface.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Dalston, joints up high may need ladders or other access, which is worth talking through when you book.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes an hour or two for a few joints, longer for a full run. In Dalston, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
Do you need gutter sealing in Dalston?
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
Keep an eye out for these signs:
- End caps that drip every time it rains
- Gaps along fascia and soffit joints
- Water dripping where gutter sections meet
- Damp patches inside below a leaking gutter
For an older house near a landmark such as Holy Trinity Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What about gutters on a second or third storey?
Low gutters are simple to reach. For higher work, tell us about access and we will confirm what’s needed.
Can you fit new guttering?
No, we reseal joints and trims. A gutter installer or roofer deals with replacement.
Gutter sealing in Dalston: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Sutton House (about 0.9 miles east) nearby, there’s older building stock in the area around Dalston as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Dalston Junction station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. As a London address, Dalston can be tricky for parking: let us know about parking bays, permits or a driveway.
