Gutter sealing in Hartley, done properly
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs, as long as the gutter is sound. We work on gutter end caps, uPVC fascias and garage door frames, and common reasons people get in touch are water running down the wall below the gutter and rain getting in around a garage door.
In a smaller place like Hartley, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
Big or small, you get the same 12-month guarantee.

What gutter sealing looks like in Hartley
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 Cobham College (about 3.9 miles east) nearby, there’s older building stock in the area around Hartley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Hartley Primary Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Longfield station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around Church of Saint Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

Which products do you use?

When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What guarantee comes with the job?

Why deal with it now?
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. In a smaller place like Hartley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What we seal
- Garage door frames
- Gutter end caps
- Roofline trims
- Soffit joints
- Gutter joints
- uPVC fascias
Surface by surface
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.
uPVC fascias
Open fascia joints look untidy and can let water in. A neat bead closes them up.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Sort out a dripping joint early
- Look for streaks or damp on the wall below gutters
- Keep ladders off the guttering
- Make sure downpipes aren’t blocked
Leave the new sealant to cure as we advise before poking or cleaning near it.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams in Hartley and across Kent. We can quote a run of properties together.
How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take an hour or two for a few joints, longer for a full run. In a smaller place like Hartley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
How to prepare
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
