Holborough Window Mastic
Our applicators work in Holborough on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
- Old mastic that has gone black or come away
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How we handle window mastic in Holborough
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 12-month guarantee on the work. If you have sealant in the wrong colour for the frame and rain getting in at the frame or under the sill, we can put it right, on composite doors, window sills and aluminium frames alike.
Around Holborough, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. In a smaller place like Holborough, 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Let us know about parking restrictions
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Advice
Quotes for window mastic in Holborough
Every job gets its own quote. These are the things that affect it:
- The amount of work
- Access and height
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
Helping us quote
When you call or email, it’s useful to know:
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Signs you need window mastic in Holborough
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- A bead that does not match the frame
- Old mastic that has gone black or come away
If you live in an older home near Church of the New Jerusalem, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Holborough
Can you help a landlord with a rental near Snodland station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Holborough?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we’ll choose accordingly.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Holborough homes and the weather
With historic houses such as Starkey Castle (about 1.9 miles north) nearby, there’s older building stock in the area around Holborough 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Valley Invicta Primary School at Holborough Lakes are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Snodland station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Holborough is about 4 miles west of Chatham, in Kent.

We cover 922 towns and villages across Kent, from the larger towns to small villages. Our London page covers work nearby (26 miles or so).

Local landmarks in Holborough
Locally, jobs take us to homes and businesses close to The Monks Head pub, Holborough Marshes and The Holmesdale School, among other places. The nearest railway station is Snodland station, roughly 0.5 miles south. Well-known places in the area include St. Catherine's Hospital (4.2 miles north-east) and Leybourne Castle (2.5 miles south-west). Not far away are Blue Bell Hill and Burham Down.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. In an older home around Holborough, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
After the cure time, these simple habits help:
- Use gentle cleaners on frames and sealant
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
- Don’t paint over the silicone
Most silicone sealants will not 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.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
