What affects the cost of gutter sealing
We don’t publish a price list. The quote depends on:
- Which sealant suits the joint
- Mould in or behind the old joints
- The size of the job
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To make quoting easier, please include:
- Where the job is, and your postcode
- Whether it has been sealed before
- The rough size of the job
- If it’s domestic, commercial or a hotel

Gutter sealing in Askett, done properly
We do not replace gutters, fascias or roofs. Sealant fixes joints and it cannot mend broken brackets, split sections or blocked downpipes. If you have internal damp traced to a gutter joint and fascia boards with gaps between them, we can put it right.
Older homes in small places like Askett may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months, in Askett and everywhere else we cover.

How to look after the new joints
After the cure time, these simple habits help:
- Clear leaves and moss from the gutters
- Keep downpipes clear
- Rest ladders on the wall, not the gutter
- Look along the fascias for open joints
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
Questions from Askett
Can you do gutter sealing in Askett?
Yes. Our work covers London and the South East, and Askett is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Do you work for landlords with property near Monks Risborough station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Where do you work from?
Mr Mastic is based in Crawley. We cover Askett and the rest of Buckinghamshire, along with the rest of our area.
Will sealant fix a dripping gutter joint?
In many cases, yes. A clean, dry joint resealed with gutter sealant generally stops the drip. A split or warped section needs replacing.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We will confirm the access for higher gutters once we know more.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
Common problems we fix in Askett
Sagging sections pull joints apart. Sealing will not hold if the gutter keeps dropping, so the gutter needs refixing first.
It’s worth asking for a quote if you see:
- Old gutter sealant that has let go
- Old sealant on roofline trims that has split
- Rain getting in around a garage door
- Internal damp traced to a gutter joint
If you live in an older home near Church of St Dunstan, an extension built onto an older house moves differently, and the joint between them takes the strain.
Comparing quotes
- How much experience the applicator has
- How the surfaces are prepared before sealing
- Are they insured?
- Whether they seal over old material or remove it
Why deal with it now?
Sealant will not clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. Where a wall is exposed, as many are in small places like Askett, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from an hour or two to a few hours, depending on the size of the job. Somewhere as small as Askett, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
