Commercial mastic work in Wallington
Sealant joints are easy to overlook until one lets water in, and on a working site that normally surfaces as a leak, a stain or a complaint from occupiers. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you are dealing with messy, uneven beads from earlier work that let the building down and mouldy silicone around WCs, urinals and vanity tops, we can help. Most enquiries from Wallington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Occupied buildings in Wallington need the work phased: we agree the order with you and hand back each area with its cure time.
Around smaller places such as Wallington, small firms often work from converted barns, yards and rural units. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- A failed roof covering or waterproofing membrane
- Faulty windows rather than failed perimeter sealant
- A dripping trap, valve or pipe behind a fitting
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.

For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Common questions from Wallington clients
Does a hotel in Wallington need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Will you take on work at estates like Broadcut Retail Park, close to Wallington?
Yes. Our area takes in Wallington and its surroundings, with estates and business parks such as Broadcut Retail Park included. Send details of the unit and the work through our quote form for a quick quote.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Is failed sealant stripped out, or sealed over?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you cover Wallington?
Yes. Wallington falls within our area, and you can call the office on 01277 525 020 or send details through our quote form to get started.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Keep washroom and kitchen extraction working
- Log reseals in the O&M or maintenance records
- Check joints after other trades have worked nearby
- Deal with small splits before they become leaks
Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. Where work has disturbed a joint, just ring 01277 525 020 or email us for a quote.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
Signs you need commercial sealant contractors in Wallington
External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.
What tends to prompt an enquiry:
- Window and door perimeter joints that have cracked open
- Leaks that seem to come through a sealant line
- Untidy joints in a reception, shop floor or lobby
- Wall and floor joints that have lost their seal
For premises near Fareham station (1 mile west of Wallington), footfall is part of the plan: work is phased so shops and offices keep trading.
