Facade sealing near Netherfield

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

Facade sealing in Netherfield

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. We work on shopfront frames, coping and flashing joints and stone and brick facade joints, and the failures we’re asked to look at most are water coming in around window frames and new sealant peeling off old mastic. A single leaking joint is often how a building in Netherfield first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near Netherfield, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why deal with it now?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. For buildings around smaller places like Netherfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Looking after the joints

For the best life from the joints:

  • Brief window cleaners about newly sealed joints
  • Investigate damp beside windows promptly
  • Record the product and colour used on each elevation
  • Add perimeter sealant to planned maintenance checks

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.

Common questions from Netherfield clients

Can you work at a site such as Vinehall Business Centre, by Netherfield?

Yes, sites like Vinehall Business Centre are within our area, along with the rest of Netherfield. Photos and a short description are enough for a first look.

Is Netherfield too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Commercial clients in Netherfield

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Different surfaces, different methods

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Facade sealing around Netherfield: points for this area

Netherfield sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 45 miles from Netherfield. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

Older buildings in the area around Netherfield, such as Durhamford Manor, 3.3 miles east of Netherfield, need care when sealed: the product has to suit soft or historic materials. For contractors at a school such as Netherfield CofE Primary School, sealing has to be finished before term starts. When units on a site such as Vinehall Business Centre, 2.5 miles to the east of Netherfield, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Netherfield may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.
