Glazing silicone near Sheerness

About our glazing silicone in Sheerness

Sealant on glazing doesn’t last for ever. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on conservatory frames, glass balustrade bases and glass-to-glass joints, and the jobs we see most are cracked silicone between glass panels and drips on the inside of a conservatory window.

In smaller places like Sheerness, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Looking after it afterwards

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

  • Do not leave a drip for the next storm
  • Inspect the sealant on glazing annually
  • Run a squeegee over the glass when you are done
  • Stick to mild cleaners on glass

Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.

A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.

The process

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many joints need doing. A visit to Sheerness is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. We clean and prepare the joint.
  4. New glazing silicone goes in and is finished neatly.
  5. The joints are checked before we leave.

Before we arrive

  • Move anything stored near the joints
  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed

Glazing silicone in Sheerness: local notes

Sheerness is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Rented homes near Sheerness-On-Sea station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Rose Street Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Sheerness is about 7 miles north of Sittingbourne, in Kent. Jobs in Sheerness get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Sheerness is one of 922 places in Kent where we work.

What affects the cost of glazing silicone

We do not publish a price list. What we look at:

  • How easy the joints are to reach
  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • How much there is to do

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Where the property is
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • The problem you’ve noticed

For glazing silicone in Sheerness, call 0345 464 0079 or email us. Tell us what the problem is and where, and we’ll agree the price before any work begins.

Sheerness: your questions answered

Is Sheerness within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is glazing silicone in a coastal place like Sheerness any different?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Is balustrade sealant something you do?

We can, if the base joint is sealed. Send us photos and we’ll take a look.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before resealing.

When is the sealant fully cured?

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

Where is Mr Mastic based?

We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Why deal with it now?

A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If the roof is the problem, we’ll say so. In a smaller place like Sheerness, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

When to call us in Sheerness

On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.

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

  • Cracked silicone between glass panels
  • Water escaping where a screen meets the wall
  • Split or lifting silicone on glass
  • Leaking glazing joints on a rooflight

If you live in an older home near Parish Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions to ask before booking

  • What the cure time is
  • What insurance they hold
  • What product goes in the joint
  • Who turns up on the day
