Gutter sealing in Reading

A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. Common call-outs are for internal damp traced to a gutter joint and quick sealant fixes on gutters that didn’t last, on gutter end caps, uPVC fascias and roofline trims.

A place the size of Reading has buildings of every age, from older brick terraces to modern blocks with rendered or clad walls. Newer buildings rely on sealed movement joints, while older ones need their gutters, fascias and trims kept tight.

A 12-month guarantee comes as standard.

FAQs for Reading

Can you help a landlord with a rental near Reading West station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.

Is there a guarantee on gutter sealing in Reading?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Do you work on high-level gutters?

That depends on the building. Let us know the height and the ground below and we will confirm what’s needed.

Is sealing fascia joints something you do?

Yes. We seal open joints along fascias and soffits in a matching colour.

Do you clean gutters?

The joints we seal are cleaned out and any debris nearby is cleared. Cleaning the whole run is a different job.

Where is Mr Mastic based?

We are based in Crawley, and we cover South East England, London and all of Scotland.

Does someone need to be in?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Can I choose the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

Work for landlords, hotels and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

How the visit works

Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from an hour or two to a few hours. Commercial jobs in Reading can be planned out of hours where a building can’t close, and homes are booked within our usual hours, Monday to Saturday.

  1. We find where the water is coming from and check the gutter is sound.
  2. We remove the old sealant and clean the joint.
  3. The joint is dried before sealing.
  4. A gutter sealant is applied to the joint.
  5. We check the run and clear debris near the joints.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Mention any tricky access
  • Tell us about any water getting in

Advice

Signs you need gutter sealing in Reading

Leaves and moss hold water in the gutter. Water that cannot drain works its way through a weak joint and leaks out.

It’s worth asking for a quote if you see:

  • Open joints in fascias and soffits
  • Old gutter sealant that has let go
  • Stop ends leaking at the end of a run
  • Water running down the wall below the gutter

If you let a flat or house near Reading West station, leaking gutter joints on a rental are best caught before they stain the walls.

Choosing a sealant specialist

When it isn’t the sealant

We won’t take on work that won’t last, so these are the limits:

  • A gutter length that has split
  • Sagging gutters or broken brackets
  • Leaks from the roof rather than a joint

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Where we work in Reading

  • uPVC fascias
  • Gutter end caps
  • Roofline trims
  • Gutter joints
  • Soffit joints
  • Garage door frames

Surface by surface

Soffit joints

Soffit joints are sealed in a colour to suit, where one is available.

Gutter joints

A dripping joint doesn’t always mean a failed gutter. Sealing the joint often stops it.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Look along the fascias for open joints
  • Clear leaves and moss from the gutters
  • Watch the wall under the gutters for staining
  • Look at the gutters while it’s raining

Keep downpipes clear so the gutter can drain. Blockages push water back along the gutter.

Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it.

Gutter sealing in Reading: local notes

Historic houses like Mapledurham House (about 3.6 miles north-west) are a reminder that the area around Reading has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near All Nations Christian Centre, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Coley Primary School, larger buildings have long runs of movement joint that eventually need resealing.

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
