Do you hold any approvals?

Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
About our gutter sealing in Lower Upnor
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. Typical jobs include garage door frames letting rain in and old gutter sealant that has let go, on uPVC fascias, garage door frames and gutter joints.
Around Lower Upnor, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, 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, then guaranteed for a year.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Get a dropping gutter looked at quickly
- Keep ladders off the guttering
- Check fascia and soffit joints for gaps
- Sort out a dripping joint early
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
What happens if it’s left?
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Older cottages and farmhouses around Lower Upnor can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Outside joints around Lower Upnor
Lower Upnor is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Strood station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near St Philip & St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The problems people normally mention when they call include:
- End caps that drip every time it rains

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes an hour or two for a few joints, longer for a full run. Somewhere as small as Lower Upnor, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
