Window mastic in Great Burgh, done properly

Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you’re dealing with water coming in at the bottom corners of a door and mastic that’s falling out in pieces, we can help, on timber windows & doors, uPVC windows and patio & French doors alike.

Houses in smaller places like Great Burgh can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

You get a one-year guarantee, the same in Great Burgh as everywhere else we work.

Great Burgh questions

Can you help a landlord with a rental near Tattenham Corner station?

Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.

Do you cover smaller places like Great Burgh?

Yes. Great Burgh is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can you quote for more than one area?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Do you seal inside as well as outside?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.

Where are you based?

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

Is the new sealant paintable?

Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Different surfaces, different methods

Patio & French doors

Heavy door frames can move more than windows. The sealant must cope with it.

Window sills

The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

Landlord and commercial work in Great Burgh

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

If you manage several properties in or around Great Burgh, jobs at different addresses can be quoted together. Send us the addresses and the work at each.

What happens on the day

On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a couple of windows and a door. A visit to Great Burgh 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. First we look at every frame and agree the list.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Deep gaps are filled with backing rod to set the depth.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Every joint is checked before we leave.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • Keep children and pets away from the work area

How to get a quote

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.

What we’re called out for in Great Burgh

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.

These are the problems we’re asked about most:

  • Mastic that has split away from the wall
  • Mastic that is falling out in pieces
  • Cold air getting in at the frame edge
  • Rain getting in at the frame or under the sill

For an older house near a landmark such as St Mark, the joint between an old wall and a newer frame is normally the first place rain gets in.

Questions to ask before booking

  • Who does the work, and how experienced they are
  • What product goes in the joint
  • How the surfaces are prepared before sealing
  • How long to leave it before use

Our hiring checklist

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Avoid harsh chemicals near the mastic
  • Wipe condensation off the frames
  • Clean frames with a soft cloth and soapy water
  • Keep jet washers away from the mastic

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Frames and glazing around Great Burgh

With historic houses such as Fitznells Manor (about 3 miles north) nearby, there’s older building stock in the area around Great Burgh as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Schools such as Shawley Community Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Tattenham Corner station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What affects the cost of window mastic

We quote each job individually. This is what makes a difference:

  • How many rooms, windows or areas are involved
  • The type of sealant required
  • Any mould that needs treating
  • When we can work, for business premises

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • What’s wrong with the joints now
  • The address or postcode of the job

Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

What sealant work cannot fix

We will not take on work that will not last, so here’s what sealant cannot put right:

  • Faulty window hardware
  • Rotten timber, which needs a joiner first
  • A failed sealed unit that has misted up

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
