Monk's Hill Window Mastic
We cover Monk's Hill for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
Window mastic in Monk's Hill, done properly
Around Monk's Hill we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, window sills and timber windows & doors, and people most often call us about rain getting in at the frame or under the sill and old mastic that has gone black or come away.
In a village or hamlet like Monk's Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with a 12-month guarantee.

What affects the quote in Monk's Hill
Your quote is based on your job. We take into account:
- When we can work, for business premises
- The product the joint needs
- How much there is to do
- Access and height
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
How the job changes by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Landlords, agents and businesses in Monk's Hill
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Signs you need window mastic in Monk's Hill
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Signs it’s time to call us include:
- Black, perished sealant on frames
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
For site and facilities teams at buildings such as Smarden Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What guarantee comes with the work
- How the colour is chosen
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere like Monk's Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

How to look after the new joints
A little care helps the new joints last. We recommend:
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Keep paint off silicone joints
- Don’t use solvent cleaners on the joint
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Frames and glazing around Monk's Hill
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.
For an older house near a landmark such as Church of St Michael, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Headcorn station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
