Glazing silicone in Mill Hill

Landlord and commercial work in Mill Hill

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Glazing silicone in Mill Hill, done properly

We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. We work on shower screens, glass balustrade bases and glass-to-glass joints, and common reasons people get in touch are conservatory leaks at frame and glazing joints and silicone pulling away from the glass.

Homes around Mill Hill range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.

Big or small, it’s backed by our 12-month guarantee.

Looking after it afterwards

Aftercare is simple:

  • Do not leave a drip for the next storm
  • Don’t use a blade near the sealant
  • Use gentle products around the joints
  • Open vents or windows to let moisture out

Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.

Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.

What affects the cost of glazing silicone

We don’t publish a price list. The quote depends on:

  • The number of rooms or windows
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • The type of sealant required

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What we need to know

To make quoting easier, let us know:

  • Where the property is
  • The rough size of the job
  • Whether it’s a home or a business
  • The problem you’ve noticed

Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job.

What we do, step by step

There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for most jobs, including the tidy-up. Parking around Mill Hill is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We start by finding the leak and making sure sealant is the cause.
  2. The old sealant is removed from the glass and frame without scratching them.
  3. Surfaces are cleaned with a solvent suited to glass and the 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.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work
  • Move anything stored near the joints

Advice

Why act early in Mill Hill

If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly, so you can call the right trade. Homes in smaller places like Mill Hill can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Do you need glazing silicone in Mill Hill?

Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.

Most people get in touch after spotting something like this:

  • Leaks where conservatory glass meets the frame
  • Failed sealant around rooflight glass
  • Leaks from the base of a shower screen
  • New silicone smeared over old sealant

Letting a property close to Walmer station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What to look for in a quote

  • How long to leave it before use
  • What happens if they find a problem under the old sealant
  • What insurance they hold
  • How much experience the applicator has

10 questions to ask before you book

Frames and glazing around Mill Hill

Mill Hill is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Homes close to St Richard include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as St Mary's Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Your questions about glazing silicone in Mill Hill

Will you come out to Mill Hill?

Yes, Mill Hill is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I let a flat near Walmer station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

Will resealing stop my conservatory leaking?

It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you fit new glass or sealed units?

We don’t replace glass. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.

Is the work guaranteed?

You get our 12-month guarantee on all our work.
