What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Working within restricted access windows
- The total length or number of joints
- Whether old sealant has to be cut out first
- The size and state of each joint
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Any dates the work must fit around
- Where the site is, with the postcode
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email a schedule or drawings.

What else we do in Aldwych
Keeping the joints sound
To get the most from the new sealant:
- Keep racking legs and heavy point loads off floor joints
- Put movement joints on the planned maintenance inspection round
- Clear dirt from joint lines during routine cleaning
- Look over external and deck joints after a hard winter
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
Surface by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For a job in Aldwych, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or send photos by email.
Advice
FAQs: Aldwych
Will you take on work at estates like Grand Vitesse Industrial Estate, close to Aldwych?
Yes. We cover Aldwych and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. A few photos and the unit address let us price the work.
Is a hospital such as Royal London Hospital for Integrated Medicine somewhere you can work?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
When to call us in Aldwych
Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
Clients normally get in touch after noticing one or more of the following:
- Hardened, cracked sealant on exposed facades
- Layers of sealant in a movement joint
- Torn sealant in brick or block movement joints
- Damp inside where a wall movement joint has failed
For an occupier at a site such as Grand Vitesse Industrial Estate (0.9 miles south-east of Aldwych), the joints at loading doors and dock levellers normally see the hardest wear.

Why act early in Aldwych
Resealing is typically the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
