What affects the quote in Sewardstone
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The number and length of the joints
- When we can work, for business premises
- The type of sealant required
- Whether there’s mould to deal with
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
When you call or email, it’s useful to know:
- Whether it has been sealed before
- The address or postcode of the job
- Pictures of the joints, sent by email
- The problem you’ve noticed
For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Gutter sealing in Sewardstone, done properly
We work across Sewardstone on leaking gutter joints and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we’ll confirm what’s needed. We work on gutter joints, roofline trims and gutter end caps, and people most often call us about failed sealant on a garage door frame and old sealant on roofline trims that has split.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
All our work is covered by our 12-month guarantee.

- Boards that have decayed or split
- Blocked downpipes
- Cracked, split or warped gutter sections
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Leave it or put it right?
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How the job changes by surface
uPVC fascias
Open fascia joints look untidy and can let water in. Sealing them closes the gap.
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
Sewardstone: your questions answered
Do you cover Sewardstone for gutter sealing?
Yes. Our work covers London and the South East, and Sewardstone is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Enfield Lock station?
Yes. We work for landlords and letting agents as well as householders. 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 take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you clean gutters?
We clear debris near the joints because the joint must be clean. Cleaning the whole run is a separate job.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Do you work on high-level gutters?
Low-level work is easiest. We will confirm the access for higher gutters once we know more.
Do you guarantee gutter sealing?
Our 12-month guarantee covers every job, gutter and fascia work included.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Sewardstone and the rest of Greater London.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on the number of joints and the access. In Sewardstone, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Clear the area around the work

Sewardstone buildings and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
For landlords with property near Enfield Lock station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Managing a site like Prince of Wales Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. As a London address, Sewardstone can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
