Questions we are asked in Lordington
Is Lordington too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you work for managing agents with blocks near Southbourne station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Mastic sealing in Lordington
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Lordington carry our 12-month guarantee. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and the failures we are asked to look at most are water getting in round frames after rain and old repairs sealed over failed mastic. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lordington, preparation and product choice get the time they need.
Rural conversions near places like Lordington often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.

Signs you need mastic sealing in Lordington
Frames, panels and masonry expand and contract through the year, 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.
Look out for the following:
- Failed external movement joints
- Communal area joints that look neglected
- Window mastic that has split and shrunk
- Water getting in round frames after rain
If you own or manage units on a site such as Hambrook Business Park, 1.4 miles south of Lordington, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
What your quote should include
- Proof of insurance
- How the existing material will be dealt with
- How the joint faces will be prepared and primed
- Their pre-qualification and accreditations
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

What affects the price in Lordington
Quotes vary with the job. It mainly depends on:
- Phasing around occupants
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- The site address and postcode
- The product your specification calls for
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Diagnose, treat, sign off

Advice
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Converted and older buildings near places like Lordington tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- Colour agreed before work starts
- One contact handling all your sites
- Constructionline member for supplier checks
- Over 20 years of commercial sealing

Lordington lies roughly 55 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
