What happens on the day

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for most jobs, including the tidy-up. For a job in Mortimer, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, we trace the leak and check it’s coming through a sealant joint.
  2. The old sealant is removed from the glass and frame without scratching them.
  3. We clean the joint with a solvent that suits the glass and frame.
  4. We apply a neutral-cure glazing silicone and tool it smooth.
  5. The finished joints are checked and, where it’s safe, tested with water.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height
  • On commercial sites, let us know about site rules

How we handle glazing silicone in Mortimer

Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. Common call-outs are for silicone pulling away from the glass and leaks where conservatory glass meets the frame, across conservatory frames, shower screens and rooflights.

In a smaller place like Mortimer, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.

All our work is covered by our one-year guarantee, wherever you are in West Berkshire.

Why act early in Mortimer

Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. In an older home around Mortimer, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before we start.

Windows and doors in Mortimer

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stratfield Saye House (about 3.6 miles south-east) are a reminder that the area around Mortimer has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

For landlords with property near Mortimer station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as Mortimer St John's C.E. Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What affects the quote in Mortimer

Your quote is based on your job. We take into account:

  • How easy the joints are to reach
  • Whether there’s mould to deal with
  • When we can work, for business premises
  • Which sealant suits the joint

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • How we’d reach the joints
  • Any previous sealing or DIY work
  • The address or postcode of the job
  • Roughly how big the job is

We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.

Honest limits

We will always be straight with you, so here’s what new sealant will not do:

  • Failed flashing around a conservatory
  • Cracked or broken glass
  • A sealed unit that has misted inside

If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Mortimer questions

Do you work for landlords with property near Mortimer station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Do you cover smaller places like Mortimer?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Do you work for hotels and businesses?

Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

What guarantee do I get?

Our 12-month guarantee covers every job, glazing sealant included.

Do you offer different sealant colours?

In most cases you can choose. We’ll explain which colours are available.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

How long does glazing silicone take?

It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will give you a better idea when we quote.

Landlord and commercial work in Mortimer

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

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

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

When to call us in Mortimer

Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.

The problems people normally mention when they call include:

  • Rooflight joints letting water in
  • Water getting into a conservatory at the joints
  • Black or yellowed silicone on glass joints
  • New silicone smeared over old sealant

In the older streets around Mortimer Methodist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • What product goes in the joint
  • What happens if they find a problem under the old sealant
  • The length of the guarantee
  • How the colour is chosen
