Work for landlords, hotels and businesses

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

About our window mastic in Chadwell St Mary

A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We’re often asked to deal with sealant in the wrong colour for the frame and cold air getting in at the frame edge, on patio & French doors, composite doors and timber windows & doors.

Many houses in smaller places like Chadwell St Mary have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.

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

What we do, step by step

The work is kept neat and contained to the joints we are treating. Expect the work to take most of a day for a typical house, less for a few frames. A visit to Chadwell St Mary is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

How to prepare

  • Mention if the joints have been sealed before
  • Move anything stored near the joints
  • Tell us about any water getting in

Do you need window mastic in Chadwell St Mary?

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.

Keep an eye out for any of the following:

  • Mastic that is falling out in pieces
  • Gaps between the frame and the inside reveal
  • Gaps left after new windows were fitted
  • White mastic on grey or black frames

If you look after a building such as Herringham Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages.

How to choose a mastic man

How the job changes by surface

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.

FAQs for Chadwell St Mary

Will you come out to Chadwell St Mary?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is window mastic in a coastal place like Chadwell St Mary any different?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.

What information do you need?

Let us know what needs doing and where, plus photos if you have them. If we need more, we’ll ask.

Can you match the sealant to my frames?

Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all.

Is the work guaranteed?

Yes. Our one-year guarantee covers every job, inside or out.

Honest limits

Before booking, it’s worth knowing the limits:

  • Penetrating damp from a failed cavity tray or render
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Faulty window hardware

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

Joints and surfaces we work on

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

Leave it or put it right?

The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Chadwell St Mary, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Why us?

  • Anti-fungal silicone where joints get wet
  • We are fully insured
  • More than 20 years in sealant work
  • An ARBOMaster approved applicator

Frames and glazing around Chadwell St Mary

Chadwell St Mary is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Rented homes near East Tilbury station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Emmanuel Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

  • Working hours on commercial sites
  • The number and length of the joints
  • Whether there’s mould to deal with
