Facade sealing in Walton-on-Thames, done properly

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about cold air coming in at window perimeters and staining on stone next to old sealant, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Walton-on-Thames, that means joint design, primers and backing rod as standard.

Older town-centre buildings in places like Walton-on-Thames are often converted to new uses or extended, so new windows and cladding meet old masonry. Those junctions need a sealant and primer that suit both surfaces.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Town-centre premises in Walton-on-Thames may have limited parking, so tell us what’s nearby. On estates and business parks it’s usually simpler.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

Do you need facade sealing in Walton-on-Thames?

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Clients usually get in touch after noticing something like this:

  • Failed seals around shopfront and entrance frames
  • Staining on stone next to old sealant
  • Draughts around frames and panels
  • Old perimeter mastic that has dried out

Hotel extensions and refits, at places such as Oatlands Chaser Hotel, 1.1 miles south-west of Walton-on-Thames, typically run between busy periods, so the sealing is squeezed into short windows.

What your quote should include

  • Who will actually carry out the work
  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier
  • Installing or repairing glazing systems

If you are not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.

What we seal

  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Shopfront frames
  • Coping and flashing joints
  • Window and door perimeters

After the work

Once the work is signed off, these steps help:

  • Keep sills, gutters and drainage paths clear
  • Ask about asbestos in pre-2000 mastic
  • Record the product and colour used on each elevation
  • Plan facade sealing alongside redecoration

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal without guesswork.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.

Walton-on-Thames: questions and answers

Do you cover business parks and estates near Walton-on-Thames, such as North Weylands Industrial Estate?

Yes, sites like North Weylands Industrial Estate are within our area, along with the rest of Walton-on-Thames. Photos and a short description are enough for a first look.

Is hospital work, at somewhere like Walton Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you look at water coming in around a frame?

Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What do you charge?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or email us.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

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, because fresh silicone will not bond with aged silicone.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Contractors’ notes for Walton-on-Thames
