What the job involves on each surface

Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
Gutter sealing in Coates
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. We work on gutter joints, uPVC fascias and soffit joints, and people most often call us about dripping gutter ends and failed sealant on a garage door frame.
Around Coates, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
All of our work is guaranteed for twelve months, in Coates and everywhere else we cover.

How do I get a quote for gutter sealing in Coates?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Will sealant fix a dripping gutter joint?
In most cases, yes. If the gutter is sagging or cracked, sealing won’t last, and we’ll tell you.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you fit new guttering?
That is not something we do. Our work is sealing joints and replacement is a job for an installer.
Is sealing fascia joints something you do?
We do. Our work is the joints, and if a board is damaged, we will tell you.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Sort out a dripping joint early
- Clean out the gutters once or twice a year
- Have sagging gutters refixed early
- Rest ladders on the wall, not the gutter
Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours, depending on the number of joints and the access. In a small place like Coates, access is usually 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.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Related advice
What we are called out for in Coates
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
Common reasons people contact us are:
- Open joints in fascias and soffits
- Cracked sealant along roofline trims
- Old gutter sealant that has let go
- Garage door frames letting rain in
If you live in an older home near Church of St Agatha, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Comparing quotes
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- How the colour is chosen
- How much experience the applicator has
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the quote in Coates
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- Working hours on commercial sites
- The amount of work
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- Whether it’s a home or a business
- How we’d reach the joints
To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.
Outside joints around Coates
With historic houses such as Bignor Roman Villa (about 2.1 miles south) nearby, there’s older building stock in the area around Coates 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Pulborough station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. For site and facilities teams at buildings such as Fittleworth CofE Village School, larger buildings have long runs of movement joint that eventually need resealing.
