How we handle gutter sealing in Exton

We do not replace gutters, fascias or roofs. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on roofline trims, soffit joints and uPVC fascias, and the jobs we see most are stop ends leaking at the end of a run and rain getting in around a garage door.

External sealant needs dry, clean surfaces, so work around Exton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Check the gutters during heavy rain
  • Check fascia and soffit joints for gaps
  • Sort out a dripping joint early
  • Do not leave a sagging gutter

If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.

Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.

Common problems we fix in Exton

Sealant laid on a wet or dirty joint fails early. Rushed repairs often do not last long for this reason.

Look out for any of the following:

  • Water running down the wall below the gutter
  • Gaps along fascia and soffit joints
  • Dripping gutter ends
  • Damp on an inside wall under a dripping gutter

For site and facilities teams at buildings such as Meonstoke Church of England Infant School, its movement joints, gutters and trims need looking after like any other building’s.

Questions to ask before you book

  • What preparation is included
  • Which colour the sealant will be
  • What happens if they find a problem under the old sealant
  • When the joint can take water or movement

Choosing a sealant specialist

Why act early in Exton

A new garage door is not needed for a leaking frame. Sealing the frame usually stops it, if the frame itself is sound. In a small place like Exton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why Exton customers choose us

  • More than 20 years in sealant work
  • Old sealant always removed completely
  • Domestic, commercial and hotel work
  • Arbo and Everbuild products

Gutter sealing in Exton: local notes

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hinton Ampner House (about 4.2 miles north) nearby, there’s older building stock in the area around Exton as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

Homes close to Church of St Peter and St Paul include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you work on high-level gutters?

Low gutters are simple to reach. For higher work, tell us about access and we’ll confirm what’s needed.

Is it messy?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

When is the sealant fully cured?

It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.

Is gutter cleaning part of the job?

We clear debris near the joints, so the sealant can bond. Cleaning the whole run is a separate job.

Where is Mr Mastic based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

How the visit works

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take an hour or two for a few joints, longer for a full run. Somewhere like Exton needs a little journey planning: 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. Old sealant and dirt are removed from the joint.
  3. The joint is dried, because sealant will not bond to a wet surface.
  4. We seal the joint with a sealant made for gutters and outdoor use.
  5. The run is checked and any debris near the joints is cleared.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about earlier repairs to the joints
