FAQs for Ryde

Can you help a landlord with a rental near Ryde St Johns Road station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Is external mastic in a coastal place like Ryde any different?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

When is the sealant fully cured?

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

How long will you be here?

A typical job takes a few hours to a few days, depending on the length of joint and the access. We will confirm how long when we quote.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.

Are you insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

How often do external joints need resealing?

It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

How we handle external mastic in Ryde

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on render & cladding joints, concrete & block and façade panels, and people most often call us about weathered mastic that no longer stretches and weeds or debris growing in open joints.

Plenty of homes in a town like Ryde have been extended, and the joint where new wall meets old is a classic place for water to get in. Getting the joint depth right matters as much as the sealant itself.

Each job carries a 12-month guarantee, large or small.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building. Parking in a town like Ryde 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 look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

How to prepare

  • Mention any tricky access
  • Mention any parking rules near the property
  • Keep children and pets away from the work area

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Show decorators and builders where the movement joints are
  • Do not let climbing plants root in the sealant
  • Check external joints each spring
  • Wash walls gently around the sealant

Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.

Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.

DIY sealant or a professional job?

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

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Why it’s worth doing now in Ryde

Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In a family home in Ryde, 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. Left alone, that means rot, damp and a bigger repair.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Ryde buildings and the weather

Ryde is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Nunwell House (about 2.8 miles south) nearby, there’s older building stock in the area around Ryde as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

In the older streets around All Saints' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Ryde St Johns Road station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Dover Park Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

What we cannot put right

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Cracking across the wall rather than at a joint
  • Damp that isn’t coming from the joint
  • Render that’s blown, hollow or coming away

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
