Gutter sealing in Graveley
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. We work on gutter end caps, garage door frames and soffit joints, and common reasons people get in touch are open joints in fascias and soffits and water dripping where gutter sections meet.
Somewhere as small as Graveley, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, you get the same 12-month guarantee.

What else we do in Graveley
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Watch the wall under the gutters for staining
- Clean out the gutters once or twice a year
- Do not leave a sagging gutter
- Deal with a drip before winter
Keep downpipes clear, so water can get away. A blocked pipe backs water up to the joints.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
Why act early in Graveley
Replacing fascias because of open joints is normally unnecessary. A neat seal closes the gaps if the boards are sound. In a small place like Graveley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
