Gutter sealing in Great Missenden
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We work on uPVC fascias, roofline trims and soffit joints, and the jobs we see most are drips from gutter joints and end caps and dripping gutter ends.
Somewhere as small as Great Missenden, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee.

Why deal with it now?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Cleaning out and drying the joint first is what makes it last. Older cottages and farmhouses around Great Missenden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Problems with the roof covering
- Water backing up from a blocked pipe
- Gutters that have dropped or pulled away

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Gutter sealing in Great Missenden: local notes
Historic houses like Hughenden Manor (about 4.2 miles south-west) are a reminder that the area around Great Missenden 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of Saints Peter and Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Great Missenden CofE Combined School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Great Missenden within the area you cover?

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Yes. Mr Mastic is an ARBOMaster approved applicator.

Yes. Several rooms, windows or areas can go on one quote.
