Blendworth Gutter Sealing
Our applicators work in Blendworth on sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old sealant removed completely, joints prepared properly.
- Old gutter sealant that has let go
- Fascia boards with gaps between them
- Cracked sealant along roofline trims
Why deal with it now?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Cleaning out and drying the joint first is what makes it last. Where a wall is exposed, as many are in small places like Blendworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.
What you get with us
- Arbo and Everbuild products
- Over 20 years’ experience

- Tidy, careful work
Gutter sealing for homes and businesses in Blendworth
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where possible. If you have streaks down the brickwork from a leaking joint and garage door frames letting rain in, we can help, on uPVC fascias, gutter joints and gutter end caps alike.
Around Blendworth, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Big or small, you get the same one-year guarantee in Blendworth and across Hampshire.

What else we do in Blendworth
What the job involves on each surface
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Sagging gutters or broken brackets
- Leaks from the roof rather than a joint
- Rotten or damaged fascia boards
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have 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.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Deal with a drip before winter
- Rest ladders on the wall, not the gutter
- Don’t leave a sagging gutter
- Look at the gutters while it’s raining
Clear the gutters once or twice a year, so water drains away past the joints. Water left in a gutter tests every joint.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
What gutter sealing looks like in Blendworth
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Uppark (about 4.8 miles north-east) nearby, there’s older building stock in the area around Blendworth as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Horndean Church of England Junior School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Rowlands Castle station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. In the older streets around Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Do you work for landlords with property near Rowlands Castle station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is Blendworth within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
How do I get a quote for gutter sealing in Blendworth?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email and let us know what needs doing and where.
Can you reach high gutters?
Single-storey and low-level gutters are straightforward. If it’s higher up, let us know and we will confirm the access.

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
