Can parking be tricky for a visit in Ratcliff?
Parking in Ratcliff, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
How do I get a quote for window mastic in Ratcliff?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
How long will my window job take?
Allow a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Window mastic for homes and businesses in Ratcliff
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have hard, cracked sealant around windows and leaking joints at the ends of sills, we can put it right.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Quotes for window mastic in Ratcliff
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The amount of work
- Which sealant suits the joint
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- The problem you’ve noticed
- How many joints, rooms or windows are involved
Every job is quoted individually. Simply call 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, 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.
Why it’s worth doing now in Ratcliff
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Ratcliff. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any tricky access
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Looking after it afterwards
Looking after new joints is easy:
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Air rooms to keep condensation down around windows
Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Honest limits
To be straight with you, some problems need a different trade:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal

Windows and doors in Ratcliff
With historic houses such as Mansion House (about 1.9 miles west) nearby, there’s older building stock in the area around Ratcliff 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Limehouse station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Marion Richardson Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Royal Foundation of St Katharine, the joint between an old wall and a newer frame is usually the first place rain gets in.
