Trusted window mastic in Westfield

What window mastic looks like in Westfield

With historic houses such as Durhamford Manor (about 3.3 miles north-west) nearby, there’s older building stock in the area around Westfield as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Doleham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Westfield School? Then its window and door frames need their mastic kept sound, just like a home’s.

Window mastic for homes and businesses in Westfield

There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you’re dealing with black, perished sealant on frames and leaking joints at the ends of sills, we can put it right, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around Westfield is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How we quote for window mastic

The quote reflects the job in front of us. We look at:

  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out
  • The number and length of the joints
  • Whether there’s mould to deal with

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

When you contact us, these details help:

  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • The type of property
  • Where the property is

We do not publish a price list. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Ventilate rooms so frames do not stay wet inside
  • Keep paint off silicone joints
  • Walk round the house once a year and look at the joints
  • Clean frames with a soft cloth and soapy water

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. Somewhere like Westfield needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, we go round the frames with you and agree the list.
  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. We tool each bead neatly and check every joint is closed.

Getting ready for the visit

  • Clear items away from the joints we are working on
  • Try not to wet indoor joints just before the visit
  • Keep children and pets away from the work area

FAQs for Westfield

Is Westfield within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work for landlords with property near Doleham station?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

How long does it take to reseal the windows on a house?

It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.

What does window mastic cost?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Will new mastic stop draughts?

Yes, where the draught is at the frame edge. We check where the draught is before any work starts.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

Do you need window mastic in Westfield?

Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.

If you can see any of these, it’s time to have the joints looked at:

  • Cold air getting in at the frame edge
  • Water coming in at the bottom corners of a door
  • Draughty joints inside around the window
  • Leaking joints at the ends of sills

For an older house near a landmark such as The Parish Church of St John the Baptist, the joint between an old wall and a newer frame is normally the first place rain gets in.

Before you book anyone

  • How the colour is chosen
  • Whether they seal over old material or remove it
  • Who does the work, and how experienced they are
  • Whether the sealant suits the joint

Choosing a sealant specialist

How the job changes by surface

Aluminium frames

Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

What we cannot put right

In fairness, some problems need a different trade:

  • A door that needs adjusting, rehanging or new seals
  • Soft or decayed wood in the frame
  • Penetrating damp from a failed cavity tray or render

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