Glazing silicone in Grove Park

Glazing silicone for homes and businesses in Grove Park

We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have leaking glazing joints on a rooflight and conservatory leaks at frame and glazing joints, we can put it right, whatever the surface.

London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Grove Park is something to talk through when you book.

We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Looking after it afterwards

So the new joints stay in good condition:

  • Run a squeegee over the glass when you are done
  • Keep conservatory gutters clear of leaves
  • Inspect the sealant on glazing annually
  • Use a gentle glass cleaner and a soft cloth

On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.

If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.

Why it’s worth doing now in Grove Park

A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone, and the leak generally returns. A proper reseal is the lasting answer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Grove Park, the repair is bigger than a sealant job.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Common questions in Grove Park

Do you work for landlords with property near Chiswick station?

Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Is parking a problem for a job in Grove Park?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Can a conservatory leak be sealed?

If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.

Is a special sealant needed for glass?

A neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Can you do several jobs on one visit?

Yes. Just list everything you need and we will quote it together.

Do you seal glass balustrade bases?

Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.

Is the work guaranteed?

Our 12-month guarantee applies on all our work.

Different surfaces, different methods

Rooflights

We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.

Conservatory frames

Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.

What affects the cost of glazing silicone

We don’t publish a price list, because jobs vary so much. What we look at:

  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • Any mould that needs treating
  • How easy the joints are to reach

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

Asking for a quote

To help us quote quickly, let us know:

  • Pictures of the joints, sent by email
  • The address or postcode of the job
  • The problem you’ve noticed
  • How many joints, rooms or windows are involved

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

What glazing silicone looks like in Grove Park

Historic houses like Chiswick House (about 0.5 miles east) are a reminder that the area around Grove Park 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 is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.

As a London address, Grove Park can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a building such as Grove Park Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. The joint is cleaned and degreased.
  4. A neutral-cure glazing silicone is applied and tooled.
  5. We check the finished joints and test with water where it’s safe.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • Let us know about parking restrictions
  • Tell us about any water getting in

Advice

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

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. Everything old must be removed first.

Signs you need glazing silicone in Grove Park

The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.

Keep an eye out for any of the following:

  • Silicone pulling away from the glass
  • Water escaping where a screen meets the wall
  • Black or yellowed silicone on glass joints
  • Failed joints on frameless glass

Rented homes near Chiswick station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Before booking anyone

  • Whether you can choose the colour
  • What insurance they hold
  • When the joint can take water or movement
  • How long the guarantee is
