How we handle sand mastic in Willingdon
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. If you have old sand mastic that has cracked, crumbled or fallen out and window mastic to renew ahead of painting, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Willingdon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Landlord and commercial work in Willingdon
Landlords and agents in Willingdon can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Do you need sand mastic in Willingdon?
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Look out for any of the following:
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
If you look after a building such as Oakwood Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- Which colour the sealant will be
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a single window, longer for several, depending on the size of the job. In a small place like Willingdon, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Move anything stored near the joints

What else we do in Willingdon
Why act early in Willingdon
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Willingdon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, 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.
Why us?
- Neat joints and a tidy finish
- A 12-month guarantee on all work
- 180+ five-star Google reviews
- Experience in homes, commercial sites and hotels
Take a look at how sealant jobs are priced or what customers say.
What affects the quote in Willingdon
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- The product the joint needs
- The number of rooms or windows
- The old material and how stubborn it is
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, have a think about:
- Roughly how big the job is
- A few pictures by email, if you can
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.
Common questions in Willingdon
Does living near the coast affect sand mastic in Willingdon?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Hampden Park station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Do not paint over the new mastic
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Willingdon homes and the weather
Willingdon is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Alfriston Clergy House (about 4.2 miles west) are a reminder that the area around Willingdon 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.
Rented homes near Hampden Park station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near The Parish Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.
