Window mastic in Gordon Hill, done properly

Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on composite doors, aluminium frames and timber windows & doors, and people most often call us about cracked internal joints between frame and plaster and whistling draughts around closed windows.

London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Gordon Hill is something to talk through when you book.

The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Your questions about window mastic in Gordon Hill

Can you help a landlord with a rental near Gordon Hill station?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Is parking a problem for a job in Gordon Hill?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Can new sealant go over the old?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Can you do the inside joint as well?

Yes. Indoors, we seal between the frame and the plaster or reveal.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Gordon Hill, along with the rest of our area.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

How it works

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of frames, longer for a whole house from start to finish. In Gordon Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Mention any tricky access
  • Move anything stored near the joints
  • Tell us about any water getting in

Related advice

When to call us in Gordon Hill

Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.

People usually contact us after spotting one of these:

  • Water coming in at the bottom corners of a door
  • Draughty joints inside around the window
  • Gaps left after new windows were fitted
  • Whistling draughts around closed windows

Homes close to St Michael & All Angels include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions to ask before booking

  • When the joint can take water or movement
  • What preparation is included
  • What happens if they find a problem under the old sealant
  • The length of the guarantee

How to choose a mastic man

What we cannot put right

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It will not solve:

  • Faulty window hardware
  • A door that needs adjusting, rehanging or new seals
  • Condensation trapped between the panes

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Frames and glazing around Gordon Hill

In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Forty Hall (about 0.9 miles north-east) are a reminder that the area around Gordon Hill has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Landlords, agents and businesses in Gordon Hill

We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.

How the job changes by surface

Window sills

Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.

Timber windows & doors

Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.

What affects the cost of window mastic

You’ll get a clear quote before any work starts. It takes into account:

  • When we can work, for business premises
  • How much old sealant there is and how hard it is to remove
  • Access and height
  • The amount of work

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Helping us quote

To help us quote quickly, let us know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
  • A few pictures by email, if you can
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Don’t paint over the silicone
  • Wipe condensation off the frames
  • Clean frames with a soft cloth and soapy water
  • Do not use solvent cleaners on the joint

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or email us.

Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
