What sealant work can’t fix

Window mastic in Hollingbury, done properly
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We work on window sills, timber windows & doors and composite doors, and common reasons people get in touch are black, perished sealant on frames and cracked or shrunken mastic around the frame.
Homes around Hollingbury range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Your job is guaranteed for a year, as with all our work.

What affects the quote in Hollingbury
Jobs vary more than people expect. The main factors:
- The size of the job
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Why deal with it now?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Hollingbury, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. For a job in Hollingbury, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Advice
Your questions about window mastic in Hollingbury
Does the coastal weather in Hollingbury affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Hollingbury within the area you cover?
Yes, Hollingbury is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is the new sealant paintable?
Most silicone can’t be painted. Let us know beforehand, and we will use a paintable product where it suits.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
How much does window mastic cost in Hollingbury?

What window mastic looks like in Hollingbury
Hollingbury is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Preston Manor & Gardens (about 1.4 miles south-west) are a reminder that the area around Hollingbury 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.
For site and facilities teams at buildings such as Carden Nursery and Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Moulsecoomb station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Hollingbury is about 2 miles north of Brighton, in Brighton and Hove.

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
What we’re called out for in Hollingbury
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The problems people usually mention when they call include:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Whistling draughts around closed windows
Preston Manor & Gardens, about 1.4 miles south-west, is one of the historic houses in the wider area around Hollingbury.
Questions to ask before you book
- Whether all the old sealant comes out first
- What insurance they hold
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
