How we handle window mastic in Arundel
Homes in Arundel have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We are often asked to deal with damp patches on the reveal after heavy rain and mastic that’s falling out in pieces, on uPVC windows, patio & French doors and aluminium frames.
Many houses in smaller places like Arundel have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep paint off silicone joints
- Do not aim a pressure washer at the joints
- Look round the frames every year or so
- Repaint timber before it’s bare
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Windows and doors in Arundel
London and the South East are among the drier parts 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 Ecclesden Manor (about 4.3 miles south-east) nearby, there’s older building stock in the area around Arundel as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Arundel station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as St Philip's Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What we do, step by step
The work is kept neat and contained to the area we’re working on. The job generally takes a few hours for a handful of frames, longer for a whole house. Parking around Arundel is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts

Advice
Do you need window mastic in Arundel?
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
The problems people usually mention when they call include:
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
For an older house near a landmark such as Trinity Congregational Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
What to look for in a quote
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- When the joint can take water or movement
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A frame that has rotted at the joint
- Broken hinges, locks or handles
- Condensation trapped between the panes

Questions from Arundel
Do you work for landlords with property near Arundel station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is Arundel within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Can you match the sealant to my frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
How do I get a quote for window mastic in Arundel?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Working hours on commercial sites
- The old material and how stubborn it is
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
