Welcome to Seal & Shield.

We are a specialist mould eradication company.

Unlike traditional damp firms, we don’t rip out plaster, remove skirting boards or inject unnecessary chemicals into your walls. Instead, we use a proven approach that works with the natural breathability of your building to eliminate mould and
help prevent it from returning.

Mould Treatment Before

Mould Treatment using IDA Solution

IDA SOLUTION, a unique method of eradicating mould for good.

I

INSULATE

Provides an insulating layer to the surface where applied. This helps capture heat from the surrounding room and raise the surface temperature reducing the likelihood of condensation forming on colder surfaces.

D

DAMP PROTECTION

Provides a damp-resistant layer while remaining fully breathable.

A

ANTI MOULD

contains a long-lasting anti-mould agent which actively inhibits mould growth on treated surfaces, helping to prevent the return of mould once the treatment has been applied.

FAQ

How does the treatment process work?

Every property is assessed individually to identify the factors contributing to mould growth. We then clean affected areas, remove existing mould contamination and apply our specialist treatment.

Unlike many traditional damp treatments, there is no need for disruptive building work, extensive plaster removal or for occupants to leave the property. Most treatments are completed with minimal disruption, providing a lasting solution rather than a temporary cover-up.

Is it expensive?

Our pricing is comparable to other professional mould treatment solutions and is tailored to each property’s specific requirements. Every treatment includes a full mould eradication process, from cleaning and removing existing contamination through to the application of our specialist IDA treatment.

As every property and level of mould growth is different, we provide a bespoke quotation following an inspection. Our aim is to deliver a long-lasting solution that offers excellent value when compared to repeated cleaning, redecorating or temporary treatments.

How long does it take?

Most mould treatments are completed within one day or less. The exact timescale will depend on the size of the affected area and the severity of the mould growth, but disruption is kept to a minimum throughout the process.

Do I have to vacate the property whilst it is being done?

No. All treatments and the IDA solution are totally water based and non-solvent.

How long will it last?

Since 2023, we have not experienced any mould regrowth in the treated areas of properties where our IDA solution has been applied. This provides confidence that the mould has been eradicated, not just temporarily hidden.

Can I paint over it in my own colour?

Yes. Once the treatment has been completed, the area can be painted or redecorated in the colour of your choice. However, we recommend waiting at least two weeks before painting to allow the IDA treatment sufficient time to fully cure and perform as intended.

P. Harris – private landlord

Seal & Shield visited my property to investigate a mould problem we’d been dealing with for years. From the initial survey to the treatment, the entire process was professional and clearly explained. Since the work was completed in January 2025, we’ve had no further issues, and the room feels noticeably warmer with no sign of mould returning. The workmanship was excellent, and I would highly recommend Seal & Shield for their outstanding service and great value for money.
