Leave it or put it right?

Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Where a wall is exposed, as many are in small places like St Margarets, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Remedial sealant for homes and businesses in St Margarets

A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have kitchen joints letting water behind the worktop and leaks that keep coming back after resealing, we can help.

In a village or hamlet like St Margarets, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in St Margarets

We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

How we quote for remedial sealant

The price is agreed before any work begins. It takes into account:

  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • Whether the work is at height

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Helping us quote

When you call or email, it’s useful to know:

  • The problem you’ve noticed
  • How we’d reach the joints
  • Photos by email, if that is easy
  • Where the property is

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Signs you need remedial sealant in St Margarets

Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

Most people get in touch when they notice one of these:

  • Sealant applied over old sealant that has lifted
  • Floor or wall movement joints that have failed
  • Worktop sealant that has shrunk and split
  • Products that weren’t meant for the joint

For landlords with property near St Margarets (Herts) station, a joint that keeps failing is best fixed properly while the property is empty.

  1. We protect the surfaces around the joint.

Advice

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Remedial sealant in St Margarets: local notes

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a building such as The Cranbourne Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as Parish Church of St Andrew, walls and floors in older homes can move, and sealant and grout show it first.
