Window mastic in Tangmere

Window mastic for homes and businesses in Tangmere

Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on timber windows & doors, patio & French doors and composite doors, and people most often call us about gaps between the frame and the inside reveal and cold air getting in at the frame edge.

Homes around Tangmere range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Surface by surface

Timber windows & doors

Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

Patio & French doors

Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.

Windows and doors in Tangmere

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Goodwood House (about 1.8 miles north-west) nearby, there’s older building stock in the area around Tangmere as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as St Andrew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Tangmere Primary Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards

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

  • Wash the frames with mild soapy water
  • Do not paint over the silicone
  • Air rooms to keep condensation down around windows
  • Keep drainage slots and sill grooves clear

A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or send us an email.

On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

The process

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. For a job in Tangmere, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First we look at every frame and agree the list.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Deep gaps are filled with backing rod to set the depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

How to prepare

  • Keep children and pets away from the work area
  • Clear the area around the work
  • Mention any tricky access

Advice

When to call us in Tangmere

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

The most common problems we see are:

  • Cracked internal joints between frame and plaster
  • Damp patches on the reveal after heavy rain
  • Mastic that has split away from the wall
  • Rushed sealant from a window installation

If you let a flat or house near Chichester station, renewing tired window mastic between tenants heads off draught and damp complaints.

Our hiring checklist

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Tangmere: your questions answered

Yes. Our work covers London and the South East, and Tangmere is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.

Will you come out to Tangmere?

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

Are you an approved applicator?

How many windows can you do in a day?

What do you need from me for a quote?

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you guarantee window mastic?

Do you take out the old sealant first?
