About our window mastic in Mickleham

The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you’re dealing with cracked or shrunken mastic around the frame and whistling draughts around closed windows, we can help, on timber windows & doors, patio & French doors and aluminium frames alike.

Mastic can only go onto a dry, clean joint, so window work in Mickleham is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from Mickleham

Can you do window mastic in Mickleham?

Yes. We work across London and the South East, and Mickleham is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.

Will you come out to Mickleham?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

When is the sealant fully cured?

Cure times vary by product and the temperature. We tell you how long to leave it before we go.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you take out the old sealant first?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Different surfaces, different methods

Patio & French doors

Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How we quote for window mastic

Jobs vary more than people expect. What affects the quote:

  • How many areas need sealing
  • Access and height
  • The size of the job
  • Whether there’s mould to deal with

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Asking for a quote

Before you ask for a quote, have a think about:

  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • The address or postcode of the job
  • Whether it’s a home or a business

We quote each job on its own. Just call 0345 464 0079 or email us with the details and send pictures if you have them.

Why act early in Mickleham

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Mickleham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

  • Colour agreed with you before work begins
  • 4.9 on Google from 180+ five-star reviews

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

What window mastic looks like in Mickleham

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Polesden Lacey (about 2.4 miles west) are a reminder that the area around Mickleham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

If you let a flat or house near Box Hill & Westhumble station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as St Michael's CofE Aided Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

What we do, step by step

We keep the work tidy and contained to the joints we are treating. Expect the work to take most of a day for a typical house, less for a few frames. In a small place like Mickleham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each frame and agree which ones need doing.
  2. We remove the old mastic and clean the frame and the wall.
  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. Finally we tidy up and check each joint.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Move anything stored near the joints
  • For indoor joints, keep the area dry beforehand if you can

How to get a quote

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.

Related advice

Signs you need window mastic in Mickleham

Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.

These are the problems we’re asked about most:

  • Whistling draughts around closed windows
  • Untidy mastic left by window fitters
  • Black, perished sealant on frames
  • White mastic on grey or black frames

In the older streets around Church of St Michael, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
