Gutter sealing in Aston

We don’t replace gutters, fascias or roofs. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. We are often asked to deal with fascia boards with gaps between them and internal damp traced to a gutter joint, across gutter end caps, soffit joints and garage door frames.

Somewhere as small as Aston, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

There’s a 12-month guarantee on every job.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Check fascia and soffit joints for gaps
  • Check that water runs out of the downpipes
  • Get a dropping gutter looked at quickly
  • Clear leaves and moss from the gutters

Have a look at the gutter during a downpour now and then. It’s the easiest time to see a leak.

If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches.

What we can’t put right

To be straight with you, there are a few things sealant will not fix:

  • Brackets that have snapped or loosened
  • Leaks from the roof rather than a joint
  • Water backing up from a blocked pipe

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

How we quote for gutter sealing

We quote each job individually. This is what makes a difference:

  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • When we can work, for business premises
  • Mould in or behind the old joints

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Asking for a quote

Photos by email are helpful but not essential. Try to tell us:

  • A few photos by email, if you can
  • If someone has resealed it before
  • The rough size of the job
  • Where the property is

Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Different surfaces, different methods

Gutter end caps

End caps take the pressure of water running along the gutter. A failed seal makes them leak.

Garage door frames

Garage door frames let rain in when their sealant fails. It’s removed and renewed.

What we do, step by step

At the end, we look at the finished work together. The visit itself normally takes anything from an hour or two to a few hours, depending on the amount of work. For a village or hamlet like Aston, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. The joint or trim is cleaned out and old sealant removed.
  3. The area is dried so the sealant can bond.
  4. We seal the joint with a sealant made for gutters and outdoor use.
  5. We look along the gutter and clear debris around the joints.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know if you’ve seen damp or leaks
  • Mention any parking rules near the property

How to get a quote

Related advice

Do you need gutter sealing in Aston?

Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.

Any of these means the joints need attention:

  • Open joints in fascias and soffits
  • Old sealant on roofline trims that has split
  • Wet patches on the wall under a gutter joint
  • Water dripping where gutter sections meet

If you look after a building such as Aston St Mary's Church of England Aided Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Our hiring checklist

Why deal with it now?

Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. Older cottages and farmhouses around Aston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

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

Why us?

  • Anti-fungal silicone where joints get wet
  • ARBOMaster approved applicator
  • Neat joints and a tidy finish
  • Full insurance on every job

Aston questions

Do older homes in Aston need their sealant replacing?

Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant will not stick to old, so the old bead has to come out completely first.

Can you help a landlord with a rental near Knebworth station?

Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint.

Can you match the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

What guarantee comes with the job?

Our 12-month guarantee covers every job.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. Our applicators cover Aston, along with the rest of our area.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Walls and rooflines in Aston

Historic houses like Aston Bury (about 0.7 miles south) are a reminder that the area around Aston 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. 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.

If you live in an older home near Parish Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Knebworth station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
