About window mastic in Milton Keynes

From a single sill to a whole house of windows, you will get a clear quote before we start. To get one, call 0345 464 0079 or email us with the number of frames and any access details for window mastic in Milton Keynes. Common call-outs are for sealant in the wrong colour for the frame and whistling draughts around closed windows, across window sills, patio & French doors and composite doors.

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a morning for a couple of windows and a door, depending on the size of the job.

  1. First we look at every frame and agree the list.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

How we quote

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Frames and weather across Milton Keynes

Across Milton Keynes, from Bletchley, Newport Pagnell and Bletchley and Fenny Stratford outwards, frames range from older timber to modern uPVC and aluminium. The mastic around all of them ages, and it’s usually the first thing to let the weather in.

From Victorian terraces to post-war new towns and modern estates, homes across the South East and London cover every era. Each needs the right sealant for its age and materials.

Milton Keynes: For an older house near a landmark such as Church of Christ the Cornerstone, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Milton Keynes Central station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Quotes for window mastic in Milton Keynes

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

  • Whether old sealant or filler has to be cut out
  • The product the joint needs
  • Whether the work is at height
  • The number of rooms or windows

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. Your quote takes all of that into account.

What we need to know

When you call or email, these details help:

  • Photos by email, if that is easy
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • Whether it has been sealed before

Keeping the joints in good condition

Aftercare is simple:

  • Ventilate rooms so frames don’t stay wet inside
  • Clean frames with a soft cloth and soapy water
  • Avoid harsh chemicals near the mastic
  • Walk round the house once a year and look at the joints

On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

What sealant work cannot fix

It helps to know what we cannot do:

  • Damp problems in the wall away from the window
  • Draughts through the window seals rather than the frame
  • Faulty window hardware

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

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

What we’re called out for in Milton Keynes

Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.

Look out for any of the following:

  • Rushed sealant from a window installation
  • White mastic on grey or black frames
  • Mastic that has split away from the wall
  • Old mastic that has gone black or come away

Questions from Milton Keynes

How long before the joint can be used?

It depends on the product and the conditions. Before we leave, we will tell you the cure time.

Is the new sealant paintable?

That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.

Will resealing my frames help with draughts?

If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.

Can you match the sealant to my frames?

Yes, in most cases. Mention the frame colour when you ask for a quote and we will match it as closely as we can.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in.
