DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Window mastic in Tooting Bec

A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have rain getting in at the frame or under the sill and leaking joints at the ends of sills, we can put it right.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Tooting Bec as anywhere.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Tooting Bec homes and the weather

In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For site and facilities teams at buildings such as St Boniface RC Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Tooting station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Your questions about window mastic in Tooting Bec

Can parking be tricky for a visit in Tooting Bec?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Can you do window mastic in Tooting Bec?

Yes. We work across London and the South East, and Tooting Bec is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

Can tenants book the work?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Can landlords and businesses book you?

Yes. We work in homes, commercial premises and hotels.

Do you have insurance?

Yes. We’re fully insured for every job we do.

What do you put in the joint?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.

Does someone need to be in?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

What we do, step by step

The work is kept neat and contained to the area we’re working on. The job generally takes anything from an hour or two to a full day, depending on how many frames there are. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Tooting Bec. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First, we confirm safe access to each frame.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. The surfaces are cleaned and left dry.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in
  • Mention any tricky access

An exposed front door gets wind-driven rain. Those corners get the most care.

uPVC windows

The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.

Why act early in Tooting Bec

Draughts and leaks do not 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 will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Tooting Bec, the repair is bigger than a sealant job.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Draughts through the window seals rather than the frame
  • Condensation trapped between the panes
  • A frame that has rotted at the joint

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

Where we work in Tooting Bec

  • Timber windows & doors
  • Aluminium frames
  • Patio & French doors
  • uPVC windows
  • Composite doors
  • Window sills

When to call us in Tooting Bec

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

The most common problems we see are:

  • Gaps between the frame and the inside reveal
  • Old mastic that has gone black or come away
  • White mastic on grey or black frames
  • Draughts coming in around windows and doors

As a London address, Tooting Bec can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What affects the quote in Tooting Bec

Every job gets its own quote. This is what makes a difference:

  • The product the joint needs
  • The size of the job
  • Mould in or behind the old joints
  • Whether old sealant or filler has to be cut out

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we need to know

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Where the property is
  • Whether it has been sealed before
  • The type of property
  • How we’d reach the joints
