About our window mastic in Thaxted

Around Thaxted we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, timber windows & doors and composite doors, and the jobs we see most are sealant in the wrong colour for the frame and gaps left after new windows were fitted.

In smaller places like Thaxted, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.

Patio & French doors

Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Check the mastic once a year
  • Do not aim a pressure washer at the joints
  • Wash the frames with mild soapy water
  • Air rooms to keep condensation down around windows

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.

A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

Do you need window mastic in Thaxted?

Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

Any of these means the joints need attention:

  • Sealant in the wrong colour for the frame
  • Gaps between the frame and the inside reveal
  • Water coming in at the bottom corners of a door
  • Mastic that has split away from the wall

In the older streets around Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in.

How to choose a mastic man

What happens if it’s left?

Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Thaxted, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

For landlords and businesses

Landlords and letting agents in Thaxted can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

What affects the cost of window mastic

Jobs vary more than people expect. What affects the quote:

  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites
  • The size of the job

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Asking for a quote

Before you ask for a quote, have a think about:

  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • The problem you’ve noticed
  • If it’s domestic, commercial or a hotel

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Thaxted: your questions answered

What guarantee comes with window mastic in Thaxted?

All our work, in Thaxted and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Is Thaxted in your area for window mastic?

Yes. Our work covers London and the South East, and Thaxted is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.

Is it messy?

We keep the work tidy. We protect what’s around the joints.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Do you seal inside as well as outside?

Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.

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.

Do you have insurance?

Yes. We’re fully insured.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. In a smaller place like Thaxted, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we are working on

Window mastic in Thaxted: local notes

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Horham Hall (about 1.8 miles south-west) are a reminder that the area around Thaxted 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.

For site and facilities teams at buildings such as Thaxted Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
