Window mastic for Wimbledon Chase homes and businesses

How we handle window mastic in Wimbledon Chase

There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Common call-outs are for rushed sealant from a window installation and cracked internal joints between frame and plaster, across aluminium frames, timber windows & doors and composite doors.

London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Wimbledon Chase is something to talk through when you book.

There’s a 12-month guarantee on every job, whatever its size.

What we do, step by step

There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a morning for a couple of windows and a door in most cases. For a job in Wimbledon Chase, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We start by checking each window and door with you.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. We clear up and check every joint is fully closed.

Before we arrive

  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children
  • Mention any parking rules near the property

Advice

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Use gentle cleaners on frames and sealant
  • Air rooms to keep condensation down around windows
  • Paint up to the joint, not over it
  • Keep timber frames painted

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.

Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

For landlords and businesses

Letting agents and landlords in Wimbledon Chase can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

Can I do it myself?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the cost of window mastic

There’s no set price list, because jobs vary so much. What we look at:

  • The number and length of the joints
  • The product the joint needs
  • Whether there’s mould to deal with
  • Access and height

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Helping us quote

What to tell us when you ask for a quote:

  • If it’s domestic, commercial or a hotel
  • If someone has resealed it before
  • Roughly how big the job is
  • Photos by email, if that’s easy

Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.

Different surfaces, different methods

Timber windows & doors

On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

Composite doors

Front doors take the weather head on. We pay most attention there.

What window mastic looks like in Wimbledon Chase

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. With historic houses such as Southside House (about 1 mile north-west) nearby, there’s older building stock in the area around Wimbledon Chase as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Rented homes near Wimbledon Chase station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Wimbledon Chase is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

When to call us in Wimbledon Chase

Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.

Look out for these signs:

  • Leaking joints at the ends of sills
  • Black, perished sealant on frames
  • Rushed sealant from a window installation
  • Cracked or shrunken mastic around the frame

Schools such as Wimbledon Chase Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
