FAQs: Lordswood
Is Lordswood 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. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Princess Anne Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you do internal caulk as well as external mastic?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
How we handle construction mastic in Lordswood
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you are dealing with snag items on joints that need redoing before handover and internal caulk splitting as the building dries out, we can help, on brick and block movement joints, window and door perimeters and floor and skirting junctions alike. A single leaking joint is often how a building in Lordswood 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.
On a small site around Lordswood, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
The 12-month guarantee is for workmanship rather than 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.

What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving fire stopping as compliant
- Oversized gaps that need packing or adjustment by others
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Brick and block movement joints
Mastic packages on Lordswood sites
Lordswood is within about 3 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Lordswood included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
Work at a hotel such as DoubleTree by Hilton Hotel Southampton, 1.5 miles to the north-east of Lordswood, tends to be programmed around bookings, mastic included. Building work at universities like University of Southampton (1.8 miles south-east of Lordswood) is often timed for the summer, mastic included. When units on a site such as Northbrook Industrial Estate (to the south of Lordswood) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Lordswood is about 2 miles north-west of Southampton, in Southampton. Lordswood sits inside our coverage and the rest of Southampton, with the same fixed quotes and 12-month guarantee as everywhere else. Our Southampton coverage takes in 30 places, large and small.

What else we do in Lordswood
Aftercare for building managers
A few simple habits keep the new joints working:
- Ask installers to correct oversized gaps first
- Stick to the specified sealant rather than a generic substitute
- Don’t force external sealing on a damp or frosty day
- Brief following trades on areas that have been sealed
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Why act early in Lordswood
Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Lordswood, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
- Let building users know which areas are affected
Quotes
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
What sets the cost
These are the things that shape the price:
- Travel to remote or island sites
- How much existing material needs removing
- Backing rod, priming and other preparation
- Phasing around occupants
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Access details, including height
- Specification clauses that apply
- When you need the work done
- Whether an asbestos survey exists
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email a schedule or drawings.
What the job involves on each surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
