How the visit works

The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. For a village or hamlet like Gosfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in
  • Move anything stored near the joints

About our window mastic in Gosfield

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are gaps left after new windows were fitted and black, perished sealant on frames.

Mastic can only go onto a dry, clean joint, so window work in Gosfield is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

There’s a 12-month guarantee on every job.

Gosfield homes and the weather

Historic houses like Hedingham Castle (about 4 miles north) are a reminder that the area around Gosfield has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Braintree station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Gosfield Community Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Catherine include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Gosfield: your questions answered

Do you work for landlords with property near Braintree station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Is Gosfield within the area you cover?

Yes, Gosfield is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is the new sealant paintable?

Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.

How long before the joint can be used?

Different products cure at different speeds, so please follow the time we give you when we finish.

How much does window mastic cost in Gosfield?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Why act early in Gosfield

Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Gosfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Honest limits

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Rotten timber, which needs a joiner first
  • Damp problems in the wall away from the window
  • Worn gaskets, brush seals or a door that has dropped

If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.

Surfaces we seal

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

Looking after it afterwards

Aftercare is simple:

  • Check the mastic once a year
  • Do not use solvent cleaners on the joint
  • Clear any debris from frame drain holes
  • Use gentle cleaners on frames and sealant

Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.

Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Landlords, agents and businesses in Gosfield

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

What affects the cost of window mastic

Jobs vary more than people expect. The main factors:

  • How many rooms, windows or areas are involved
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • The amount of work

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
