- Leaking gutter joints and stop ends
- Stop ends leaking at the end of a run
- Gaps along fascia and soffit joints
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. A visit in Greenock needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Advice
About our gutter sealing in Greenock
Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. We are often asked to deal with garage door frames letting rain in and water running down the wall below the gutter, on soffit joints, roofline trims and uPVC fascias.
Harled walls are common in Scottish towns like Greenock, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Gutters and fascias here take plenty of Scottish weather too.
All our work is covered by a one-year guarantee.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Glance at the soffit joints now and then
- Clean out the gutters once or twice a year
- Get leaks sealed before the wet months
- Make sure downpipes aren’t blocked
Give the sealant the cure time we tell you and avoid disturbing it.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
Walls and rooflines in Greenock
Greenock is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. With historic houses such as Ardgowan House (about 4.1 miles south-west) nearby, there’s older building stock in the area around Greenock 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.
Historic houses such as Ardgowan House, about 4.1 miles south-west, show how far back building around Greenock goes, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as Wellington Academy, larger buildings have long runs of movement joint that eventually need resealing.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. It won’t solve:
- Blocked downpipes
- Problems with the roof covering
- Rotten or damaged fascia boards
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Gutter end caps
- Garage door frames
- Gutter joints
- uPVC fascias
- Soffit joints
- Roofline trims
What the job involves on each surface
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Common questions in Greenock
Does the coastal weather in Greenock affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I let a flat near Drumfrochar station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you replace gutters or fascias?
That is not something we do. We seal joints; replacing gutters and fascias needs a gutter or roofline installer.
Can I do it myself?
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.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Why deal with it now?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. In flats with a shared stair in Greenock, a leak from a failed seal can affect the flat below too, and that’s much harder to put right.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why Greenock clients choose us
- Experience in homes, commercial sites and hotels
- White, clear, grey or another colour, product permitting
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet

When to call us in Greenock
Roofline sealant ages in sun and rain. It hardens, shrinks and splits over time.
Keep an eye out for any of the following:
- Damp patches inside below a leaking gutter
- Earlier gutter repairs that have peeled off
- Rain getting in around a garage door
- Old sealant on roofline trims that has split
Rented homes near Drumfrochar station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
