Window mastic in Motspur Park

Should I try it myself first?

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. All the old material has to come out first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Window mastic in Motspur Park, done properly

Homes in Motspur Park have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on patio & French doors, window sills and timber windows & doors, and the jobs we see most are water coming in at the bottom corners of a door and rushed sealant from a window installation.

Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Windows and doors in Motspur Park

Historic houses like Southside House (about 0.8 miles north-east) are a reminder that the area around Motspur Park 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. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.

For an older house near a landmark such as Christ Church New Malden, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Motspur Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What we cannot put right

To be straight with you, some problems need a different trade:

  • Faulty window hardware
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What we seal

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

How the job changes by surface

uPVC windows

uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

Aluminium frames

Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.

Why act early in Motspur Park

Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Motspur Park, the repair is bigger than the sealant job would have been.

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. Call for a quick quote and we will explain what it covers.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door, and the area is left clean. In Motspur Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away, along with any loose debris.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Advice

Signs you need window mastic in Motspur Park

A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.

People normally contact us after spotting something like this:

  • White mastic on grey or black frames
  • Cold air getting in at the frame edge
  • Black, perished sealant on frames
  • Gaps between the frame and the inside reveal

For site and facilities teams at buildings such as St Matthew's CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Before booking anyone

  • Who does the work, and how experienced they are
  • How the surfaces are prepared before sealing
  • Whether VAT is included
  • Are they insured?
