Gutter sealing in Washington
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first, then dry the joint before sealing. Typical jobs include quick sealant fixes on gutters that didn’t last and streaks down the brickwork from a leaking joint, on uPVC fascias, gutter end caps and garage door frames.
In a village or hamlet like Washington, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a 12-month guarantee.

What else we do in Washington
Your questions about gutter sealing in Washington
Do you cover Washington for gutter sealing?
Yes, Washington is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
What guarantee comes with gutter sealing in Washington?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can sealant stop a sagging gutter leaking?
It will not last. The movement opens the joint again, so the fall and brackets need sorting first.
Will you clear out my gutters?
We clean the joints we’re sealing and clear debris we find nearby. A full gutter clean is a separate service.
How much does gutter sealing cost in Washington?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Surface by surface
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Garage door frames
Garage door frames let rain in when their sealant fails. We cut it out and reseal.
Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why act early in Washington
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Around Washington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What affects the quote in Washington

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a few hours, and the area is left clean. For a village or hamlet like Washington, the journey is planned in advance: let us know about lanes, gates and parking.

Advice
Walls and rooflines in Washington
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Parham House (about 3.9 miles west) nearby, there’s older building stock in the area around Washington as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around The Parish Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as St Mary's CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.
