What affects the quote in Caring

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • Any mould that needs treating
  • When we can work, for business premises

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Roughly how big the job is
  • Whether it has been sealed before
  • Whether it’s a home or a business
  • How we’d reach the joints

Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.

About our window mastic in Caring

Behind a thin line of old mastic there’s sometimes a deep void. 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. If you are dealing with hard, cracked sealant around windows and whistling draughts around closed windows, we can help, on uPVC windows, aluminium frames and composite doors alike.

Somewhere as small as Caring, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

You get a 12-month guarantee, the same in Caring as everywhere else we work.

Why deal with it now?

Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. Older cottages and farmhouses around Caring can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Aftercare tips

So the new joints stay in good condition:

  • Air rooms to keep condensation down around windows
  • Do not aim a pressure washer at the joints
  • Keep drainage slots and sill grooves clear
  • Use gentle cleaners on frames and sealant

Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.

Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Caring questions

Do you work for landlords with property near Bearsted station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Can you do window mastic in Caring?

Yes, Caring is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.

Should I try DIY first?

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.

Can you do upstairs windows?

Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.

Do you take out the old sealant first?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new sealant bonds properly.

How long will my window job take?

That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.

How it works

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. In a small place like Caring, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we confirm safe access to each frame.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints
  • Mention any tricky access

What window mastic looks like in Caring

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. With historic houses such as Stoneacre (about 0.7 miles south-west) nearby, there’s older building stock in the area around Caring 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 landlords with property near Bearsted station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Leeds and Broomfield Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Nicholas's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What sealant work cannot fix

New sealant cannot fix everything, and we’ll tell you before we start. It won’t solve:

  • Rotten timber, which needs a joiner first
  • Damp problems in the wall away from the window
  • Misting between the panes of a double-glazed unit (that needs a new unit)

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

Joints and surfaces we work on

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
