Is resealing worth it?

Sealing over old silicone is a false economy. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. No two jobs are quite the same, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.

Landlord and trade work in Winchmore Hill

Builders use us to fix snagging damage before handover, saving last-minute replacements. We can visit several plots in one trip.

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

Should I try a DIY kit first?

We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.

You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.

Winchmore Hill questions

Do you work in Winchmore Hill?

We do. Repair technicians travel to Winchmore Hill from across the region, and the price is the same as everywhere else.

Do you do work for letting agents?

Yes, frequently. We quote for multiple addresses and fit around tenancy changeovers.

Is it worth repairing rather than replacing?

Generally, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Many landlords are happy for a repair to be arranged.

Is it safe with children and pets around?

Please keep children and pets out of the room during the visit and until it has cured. Everywhere else in the home is fine.

Can you redo someone else’s repair?

Yes, we frequently do. It can add a little time, which we include in the quote.

My seal keeps tearing. Why?

Something is moving. If it keeps happening, the support may need fixing.

How do I get a price for bath resealing in Winchmore Hill?

We give a fixed price based on photos of the damage. Send a close-up of the damage and a wider photo with your N21 postcode.

When to call us in Winchmore Hill

Joints split if the bath or tray moves, frequently because it was sealed with the bath empty.

Common reasons people in Winchmore Hill contact us are:

Unsealed corners
An untidy old seal
Water getting behind the bath or tray
Black mould in the sealant
