Window mastic for homes and businesses in Warlingham
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on uPVC windows, aluminium frames and timber windows & doors, and people most often call us about cracked or shrunken mastic around the frame and cold air getting in at the frame edge.
Many houses in smaller places like Warlingham have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
A 12-month guarantee comes as standard, so you are covered after we have gone.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a morning for a couple of windows and a door, depending on the size of the job. In a smaller place like Warlingham, 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 go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Move anything stored near the joints
- Tell us about any water getting in
- Mention any tricky access

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Warlingham, 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.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
Why book with us
- More than 20 years in sealant work
- Experience in homes, commercial sites and hotels
- Anti-fungal silicone where joints get wet
- Sealant colour chosen to suit

Window mastic in Warlingham: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Addington Palace (about 3.5 miles north) nearby, there’s older building stock in the area around Warlingham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Warlingham Village Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Warlingham is about 3 miles east of Coulsdon, in Surrey. Warlingham gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Can you help a landlord with a rental near Upper Warlingham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is the new sealant paintable?
Not normally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Patio & French doors
- uPVC windows
- Window sills
- Aluminium frames
- Timber windows & doors
- Composite doors
How the job changes by surface
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
What we’re called out for in Warlingham
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.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
Letting a property close to Upper Warlingham station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- How much experience the applicator has
- Whether VAT is included
- Whether all the old sealant comes out first
- What the cure time is
