Leave it or put it right?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Around Throwley Forstal, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Expansion joint sealing for commercial buildings in Throwley Forstal
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. The enquiries we see most involve layers of sealant in a movement joint and sealant peeling off one face of the joint, across brickwork movement joints, precast concrete panel joints and car park decks and ramps. Searching for sealant specialists in Throwley Forstal? We’ve been sealing commercial buildings since 2005.
Halls, schools and small commercial buildings near places like Throwley Forstal have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we’ll arrange a return visit.

Owners, agents and contractors
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.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Signs you need expansion joint sealing in Throwley Forstal
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it.
Any of the following is a good reason to get the joints checked over:
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
- Damp inside where a wall movement joint has failed
- Torn sealant in brick or block movement joints
Once a joint near Throwley Forstal opens up, grit and water get in and the edges start to break; we’ll tell you if the edges need repairing first.

How the job changes by surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Waterproofing layers buried beneath the sealant
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Questions we’re asked in Throwley Forstal
Will our site in Throwley Forstal have to close for joint sealing?
Typically not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.
What documents will you need to give us for a job in Throwley Forstal?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you seal on top of existing sealant?
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 work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What’s the difference between an expansion joint and a movement joint?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading while the sealant stops grit and water getting in.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area.
