Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Argos Hill and the rest of East Sussex, along with the rest of our area.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is the work guaranteed?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can new window sealant be painted?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we’ll choose accordingly.
About our window mastic in Argos Hill
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you’re dealing with a bead that doesn’t match the frame and cold air getting in at the frame edge, we can help, on uPVC windows, timber windows & doors and aluminium frames alike.
Homes in small places like Argos Hill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

When to call us in Argos Hill
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.
If you can see any of these, it’s time to have the joints looked at:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
For landlords with property near Crowborough station, renewing tired window mastic between tenants heads off draught and damp complaints.

What else we do in Argos Hill
Surface by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Frames and glazing around Argos Hill
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Wadhurst Castle (about 4.4 miles north-east) nearby, there’s older building stock in the area around Argos Hill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Rotherfield Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as The Parish Church of St Denys, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Argos Hill
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- When we can work, for business premises
- Whether the work is at height
- The amount of work
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What to tell us for a quote
When you call or email, these details help:
- How we’d reach the joints
- Where the job is, and your postcode
- Any previous sealing or DIY work
- A few photos by email, if you can
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Argos Hill, 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 we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What you get with us
- Over 20 years’ experience
- Colour agreed with you before we start
- Anti-fungal silicone where joints get wet
- 12-month guarantee on every job

Landlord and commercial work in Argos Hill

We regularly work with letting and managing agents. Tell us the address, the job and how access works.
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are.

Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
So the new joints stay in good condition:
- Don’t use solvent cleaners on the joint
- Don’t aim a pressure washer at the joints
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames don’t stay wet inside
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
