Gutter sealing for homes and businesses in Eastleigh

Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you have internal damp traced to a gutter joint and stop ends leaking at the end of a run, we can put it right, on gutter joints, garage door frames and gutter end caps alike.

Around Eastleigh, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.

Our work is backed for twelve months, in Eastleigh and everywhere else we cover.

Why it’s worth doing now in Eastleigh

You don’t need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough, if the frame itself is sound. In a family home in Eastleigh, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why book with us

  • A choice of colours where the product allows
  • Neat joints and a tidy finish
  • Colour picked to suit the job
  • We agree the colour with you first

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

What the job involves on each surface

Gutter end caps

End caps take the pressure of water running along the gutter. When their seal fails, they drip.

Garage door frames

Frame-to-brick joints face the weather. We use a sealant made for outdoor joints.

When something else is needed

In fairness, some problems need a different trade:

  • Rotten or damaged fascia boards
  • Downpipes that are blocked or broken
  • Problems with the roof covering

If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

What we seal

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

Looking after it afterwards

Looking after new joints is easy:

  • Clear leaves and moss from the gutters
  • Sort out a dripping joint early
  • Keep downpipes clear
  • Watch for drips in a downpour

Leave the new sealant to cure as we advise and avoid disturbing it.

Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.

Eastleigh: your questions answered

Do you cover Eastleigh for gutter sealing?

Yes. Our work covers London and the South East, and Eastleigh is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.

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

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we will quote it together.

Does someone need to be in?

That depends on where the joints are. Inside work needs someone to give us access.

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.

Where is Mr Mastic based?

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

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

How long does gutter sealing take?

It depends on the size of the job, but as a guide it takes a few hours, depending on the number of joints and the access. We’ll tell you when we quote.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes anything from an hour or two to a few hours. Parking in a town like Eastleigh is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. We find where the water is coming from and check the gutter is sound.
  2. The old sealant and dirt are cleaned out of the joint.
  3. The joint is dried before sealing.
  4. A gutter sealant is applied to the joint.
  5. The gutter is checked and debris around the joints cleared.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Tell us if parking is tricky
  • Mention any tricky access

What we are called out for in Eastleigh

Sagging sections pull joints apart. Resealing a sagging joint will not last, so the gutter needs refixing first.

These are the problems we’re asked about most:

  • Open joints in fascias and soffits
  • Earlier gutter repairs that have peeled off
  • Damp patches inside below a leaking gutter
  • Wet patches on the wall under a gutter joint

For an older house near a landmark such as Church of the Resurrection, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What to look for in a quote

  • Which colour the sealant will be
  • Whether the sealant suits the joint
  • How long to leave it before use
  • What guarantee comes with the work

Our hiring checklist

Gutter sealing in Eastleigh: local notes

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as South Stoneham House (about 2.5 miles south-west) nearby, there’s older building stock in the area around Eastleigh as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Managing a site like Norwood Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Eastleigh station, leaking gutter joints on a rental are best caught before they stain the walls.
