Purfleet-on-Thames Glazing Silicone
Glazing joints in Purfleet-on-Thames need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Sealant that was laid over old silicone and failed
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Glazing silicone for homes and businesses in Purfleet-on-Thames
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. We work on rooflights, conservatory frames and glass-to-glass joints, and common reasons people get in touch are glazing silicone that has cracked or come away and stained, discoloured glazing silicone.
In smaller places like Purfleet-on-Thames, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Every job comes with our 12-month guarantee, wherever you are in Thurrock.

What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Homes in smaller places like Purfleet-on-Thames can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

New sealant can’t fix everything, and we’ll tell you before work begins. It will not solve:
- A sealed unit that has misted inside

Can you help a landlord with a rental near Purfleet station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is Purfleet-on-Thames in your area for glazing silicone?
Yes, Purfleet-on-Thames is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you fit new glass or sealed units?
That’s not something we do. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Where do you work from?
Mr Mastic is based in Crawley. We cover Purfleet-on-Thames and the rest of Thurrock, along with the rest of our area.

Common problems we fix in Purfleet-on-Thames
Shower screen silicone gets wet every day. Mould grows into the bead and the joint starts to lift.
If you can see any of these, it’s time to have the joints looked at:
- A quick top-up bead that didn’t last
- Leaks from the base of a shower screen
- Water running down inside the glass
- Rooflight joints letting water in
For an older house near a landmark such as St Stephen's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Purfleet-on-Thames, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Mention any parking rules near the property

What glazing silicone looks like in Purfleet-on-Thames
Historic houses like Rainham Hall (about 3.1 miles north-west) are a reminder that the area around Purfleet-on-Thames has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Purfleet Primary Academy, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Purfleet station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
