Mastic sealing in Newhall, done properly
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks, and the failures we’re asked to look at most are draught complaints from residents or tenants and no planned programme for sealant. Searching for sealant specialists in Newhall? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Converted and older buildings in and around Newhall often put modern windows into old walls. The mastic there needs to suit both surfaces.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Common problems we fix in Newhall
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
What tends to prompt an enquiry:
- Old repairs sealed over failed mastic
- Damp patches beside frames
- Failed external movement joints
- Mastic failing across several blocks on an estate
For a school such as Newhall Primary Academy, perimeter mastic on windows and doors is a holiday job.
What your quote should include
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The terms of the workmanship guarantee

What else we do in Newhall
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For a site in Newhall, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
- Make sure the joints can be reached

Advice
Cost factors for mastic joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The total length or number of joints
- Phasing around occupants
- Site requirements such as inductions and permits
- Travel to remote or island sites
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- Drawings or a marked-up plan, if available
- Your programme or deadline
- A wide shot and a close-up of the area
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email the details over with what you know.
FAQs: Newhall
Do you work for managing agents with blocks near Harlow Mill station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Harlow Innovation Park, near Newhall, within your area?
Yes. We cover Newhall and the area around it, including industrial estates, business parks and retail parks such as Harlow Innovation Park. Photos and a short description are enough for a first look.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Different surfaces, different methods
Commercial and mixed-use buildings

Why act early in Newhall
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
