What affects the quote in Erith

Jobs vary more than people expect. The main factors:

  • How many rooms, windows or areas are involved
  • The size of the job
  • Working hours on commercial sites
  • Access and height

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • The rough size of the job

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.

Glazing silicone in Erith, done properly

Across Erith, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. If you have split or lifting silicone on glass and conservatory leaks at frame and glazing joints, we can put it right, on conservatory frames, rooflights and glass-to-frame joints alike.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.

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

Your questions about glazing silicone in Erith

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

Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Is parking an issue for glazing silicone in Erith?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Is balustrade sealant something you do?

Yes, where the base is finished with sealant. Photos help us see what’s there when you call 0345 464 0079 or email us.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Where is Mr Mastic based?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

How long does glazing silicone take?

That depends on how much there is to do, but most jobs take a few hours for most jobs. We will tell you when we quote.

Can I add another job to the visit?

Yes, we can. More than one area can be quoted together.

What the job involves on each surface

Conservatory frames

Frame joints face sun and rain all year. A fresh bead seals them again.

Glass balustrade bases

Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.

What we’re called out for in Erith

The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.

People generally contact us when they notice something like this:

  • Rooflight joints letting water in
  • Water escaping where a screen meets the wall
  • Drips on the inside of a conservatory window
  • Sealant that was laid over old silicone and failed

Erith is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions to ask before you book

  • What guarantee comes with the work
  • What insurance they hold
  • Whether VAT is included
  • Whether you can choose the colour

Our hiring checklist

Work for landlords, hotels and businesses

Letting agents and landlords in Erith can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.

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

What we do, step by step

Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most jobs, depending on the amount of work. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Erith. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We trace the leak and confirm it’s a sealant joint.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before
  • Mention any sign-in or site rules at work premises

Advice

What sealant work can’t fix

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Structural problems with a conservatory roof
  • Frames that have decayed or split
  • A sealed unit that has misted inside

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Surfaces we seal

  • Shower screens
  • Glass balustrade bases
  • Conservatory frames
  • Glass-to-frame joints
  • Glass-to-glass joints
  • Rooflights

Leave it or put it right?

You do not need new glazing because the sealant has gone. Sound glass and frames normally just need resealing, and we’ll tell you if that’s not the case. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Erith.

Rather than a set price list, 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 Erith customers choose us

  • We agree the colour with you first
  • A 12-month guarantee on all work
  • Colour picked to suit the job
  • Domestic, commercial and hotel work

Glazing silicone in Erith: local notes

Historic houses like Hall Place and Gardens (about 2.3 miles south) are a reminder that the area around Erith has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

Rented homes near Erith station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Schools such as Christ Church (Erith) CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
