Gutter sealing for homes and businesses in Newbury
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs, as long as the gutter is sound. Common call-outs are for gaps along fascia and soffit joints and garage door frames letting rain in, on roofline trims, uPVC fascias and soffit joints.
Around Newbury, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Where two materials meet, they move differently, and the sealant has to allow for it.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Newbury questions
Is there a guarantee on gutter sealing in Newbury?
All our work, in Newbury and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do gutter sealing in Newbury?
Yes. Our work covers London and the South East, and Newbury is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Is sealant enough for a gutter that has dropped?
Sealing a sagging joint will not last. A gutter installer needs to refix it, and we’ll tell you if that is what we find.
Where are you based?
Mr Mastic is based in Crawley. We cover Newbury and the rest of West Berkshire.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How long will you be here?
Typically it takes a few hours, depending on the number of joints and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
Can you seal fascia and soffit joints?
Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A gutter length that has split
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Downpipes that are blocked or broken
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

For landlords and businesses
Landlords and agents in Newbury can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
What the job involves on each surface
Garage door frames
The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we’ll tell you.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take an hour or two for a few joints, longer for a full run. Parking in a town like Newbury is normally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Clear the area around the work
How to get a quote
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.

Do you need gutter sealing in Newbury?
Debris in the gutter keeps water sitting at the joints. Standing water finds the weakest joint and leaks out.
The problems people usually mention when they call include:
- Drips from gutter joints and end caps
- Damp on an inside wall under a dripping gutter
- Fascia boards with gaps between them
- Quick sealant fixes on gutters that didn’t last
In the older streets around St Nicolas Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before booking anyone
- What insurance they hold
- Is VAT in the price?
- What product goes in the joint
- Is the old sealant removed completely?
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep an eye out for wet patches below a joint
- Rest ladders on the wall, not the gutter
- Sort out a dripping joint early
- Keep downpipes clear
Have a look at the gutter during a downpour now and then. It’s the easiest time to see a leak.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.
DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What gutter sealing looks like in Newbury
Historic houses like Shaw House (about 1 mile north) are a reminder that the area around Newbury has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Letting a property close to Newbury station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Schools such as St Nicolas C.E. Junior School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
