Window mastic in Charing Hill

About our window mastic in Charing Hill

If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. We are often asked to deal with rushed sealant from a window installation and draughts coming in around windows and doors, across uPVC windows, patio & French doors and aluminium frames.

Around Charing Hill, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

Big or small, you get the same 12-month guarantee in Charing Hill and across Kent.

Why it’s worth doing now in Charing Hill

Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Charing Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Why us?

  • A 12-month guarantee on all work
  • Any old sealant cut out fully, not covered over
  • We leave the area clean and tidy
  • Experience in homes, commercial sites and hotels

Different surfaces, different methods

Composite doors

Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

FAQs for Charing Hill

Do you cover Charing Hill for window mastic?

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

Do you work for landlords with property near Charing station?

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

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.

Can you do the inside joint as well?

Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.

Will resealing my frames help with draughts?

Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

When to call us in Charing Hill

Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

The problems people usually mention when they call are:

  • Gaps where the sill meets the wall
  • Gaps between the frame and the inside reveal
  • Untidy mastic left by window fitters
  • Water coming in at the bottom corners of a door

For site and facilities teams at buildings such as Charing Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions to ask before booking

  • Who turns up on the day
  • What the cure time is
  • Whether all the old sealant comes out first
  • What insurance they hold

10 questions to ask before you book

Charing Hill homes and the weather

Historic houses like Godinton House (about 4.2 miles south) are a reminder that the area around Charing Hill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

For landlords with property near Charing station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Charing Hill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking each window and door with you.
  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. We clear up and check every joint is fully closed.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any previous sealing or DIY attempts
