Why it’s worth doing now in Throwley Forstal
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. In a small place like Throwley Forstal, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.

About our gutter sealing in Throwley Forstal
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. If you’re dealing with internal damp traced to a gutter joint and failed sealant on a garage door frame, we can put it right.
External sealant needs dry, clean surfaces, so work around Throwley Forstal is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep an eye out for wet patches below a joint
- Look along the fascias for open joints
- Clear leaves and moss from the gutters
- Don’t lean ladders against the gutter itself
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
How we quote for gutter sealing
We quote each job individually. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- Access and height
- Whether there’s mould to deal with
- The size of the job
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
Photos by email are helpful but not essential. Please mention:
- The problem you’ve noticed
- Whether it’s a home or a business
- Roughly how big the job is
- If someone has resealed it before

For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take an hour or two for a few joints, longer for a full run. Somewhere as small as Throwley Forstal, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need sealing.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Outside joints around Throwley Forstal
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Belmont House and Gardens (about 1.1 miles north) are a reminder that the area around Throwley Forstal 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.
If you live in an older home near Church of St Michael and All Angels, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Selling station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Common questions in Throwley Forstal
Do you work for landlords with property near Selling station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Throwley Forstal?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Where do you work from?
Mr Mastic is based in Crawley. We cover Throwley Forstal and the rest of Kent, along with the rest of our area.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Different surfaces, different methods
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
Garage door frames
Frame-to-brick joints face the weather. We use a sealant made for outdoor joints.
