Grafty Green Gutter Sealing
We cover Grafty Green for sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

What we’re called out for in Grafty Green
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
Any of these means the joints need attention:
- Trim joints where the sealant has failed
- Rain getting in around a garage door
- Quick sealant fixes on gutters that didn’t last
- Drips from gutter joints and end caps
In the older streets around Church of St Nicholas, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- How the colour is chosen
- When the joint can take water or movement
- How the surfaces are prepared before sealing

Gutter sealing for homes and businesses in Grafty Green
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Sealing it is quick if the gutter is otherwise in good order. We’re often asked to deal with garage door frames letting rain in and dripping gutter ends, on garage door frames, gutter joints and soffit joints.
External sealant needs dry, clean surfaces, so work around Grafty Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee in Grafty Green and across Kent.

What affects the quote in Grafty Green
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How easy the joints are to reach
- Mould in or behind the old joints
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Whether it’s a home or a business
- Any access issues, like height or stairs
- Roughly how big the job is
We quote each job on its own. Just call 0345 464 0079 or drop us an email with the details.
What happens if it’s left?
A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp so early sealing is worthwhile. Older cottages and farmhouses around Grafty Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why us?
- Homes, businesses and hotels
- Anti-fungal silicone where joints get wet

Grafty Green questions
Do you work for landlords with property near Lenham station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Grafty Green?
Yes, Grafty Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long will you be here?
A typical job takes a few hours, depending on the number of joints and the access. We’ll confirm how long when we quote.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you replace gutters or fascias?
No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you clean gutters?
We clear debris near the joints, so the sealant can bond. Cleaning the whole run is a separate job.
Landlord and commercial work in Grafty Green
If you manage several properties in or around Grafty Green, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Make sure downpipes aren’t blocked
- Sort out a dripping joint early
- Look for streaks or damp on the wall below gutters
- Keep the gutters clear of debris
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours, depending on the number of joints and the access. In a small place like Grafty Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we trace the drip and check the gutter is not damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Advice
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Walls and rooflines in Grafty Green
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Leeds Castle (about 3.5 miles north-west) nearby, there’s older building stock in the area around Grafty Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Platts Heath Primary School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Lenham station, leaking gutter joints on a rental are best caught before they stain the walls.
