About our gutter sealing in Astwood

A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. If you’re dealing with damp on an inside wall under a dripping gutter and drips from gutter joints and end caps, we can help, whatever the surface.

Older homes in small places like Astwood may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.

All of our work is guaranteed for twelve months.

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What gutter sealing looks like in Astwood

With historic houses such as Turvey Abbey (about 3.3 miles north) nearby, there’s older building stock in the area around Astwood as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.

How it works

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes an hour or two for a few joints, longer for a full run. Somewhere as small as Astwood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the gutters, fascias and trims and agree the joints to seal.
  2. We clean out each joint.
  3. We make sure everything is dry.
  4. We apply exterior or gutter sealant and finish it neatly.
  5. The joints are checked once sealed.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

What happens if it’s left?

A new garage door is not needed for a leaking frame. Sealing the frame usually stops it. Older cottages and farmhouses around Astwood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Astwood: your questions answered

I let a flat near Kempston Hardwick station. Can you help?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Will you come out to Astwood?

Yes. Astwood is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

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.

Will sealant fix a dripping gutter joint?

Most of the time. If the gutter is sagging or cracked, sealing won’t last, and we’ll tell you.

Where is Mr Mastic based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Can new sealant go over the old?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

When is the sealant fully cured?

Different products cure at different speeds, so follow the cure time we give you when we finish.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Keep downpipes clear
  • Check fascia and soffit joints for gaps
  • Watch the wall under the gutters for staining
  • Clean out the gutters once or twice a year

Check the joints after heavy rain now and then. It’s the easiest time to see a leak.

A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.

How the job changes by surface

Garage door frames

Frame-to-brick joints face the weather. An exterior sealant suits them.

Gutter end caps

End caps are resealed where they meet the gutter, after cleaning and drying.

Signs you need gutter sealing in Astwood

Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.

Common reasons people contact us are:

  • Earlier gutter repairs that have peeled off
  • Stop ends leaking at the end of a run
  • Garage door frames letting rain in
  • Wet patches on the wall under a gutter joint
