Stone Floor and Wall Tile Frequently Asked Questions

Can we lay on existing tiles?
Yes in many circumstances, following appropriate advice. We can arrange for a member of our installation service to call you.
How thick are the stones?
The flagstones are approximately 25mm thick. The natural stone products range from 10mm to 50mm thick, with many products also available in a calibrated (even thickness) finish.
Can stones be laid inside and outside?
Yes, some ranges are suitable for both applications, but we do recommend sealing when used internally.
Do we deliver and is there a charge?
Yes we can offer a kerb side delivery; charges vary according to order size and delivery service selected. There are four types of delivery service - Within 5-7 Working Days, Named Weekday, Named Weekday AM or PM, and Saturday morning.
How are the products delivered?

They are normally delivered on a 26 tonne vehicle, this is approximately the size of a fire engine, the products are packed in wooden crate or pallets and will be off loaded onto the nearest hard standing area, this may be on the drive or the kerbside. It is therefore important that you advise us of any restrictions you may be aware of these include height restrictions, width restrictions on approach roads and driveways, gravel drives etc.

What are the replica flagstones made of?
A mix of stone aggregates and cement.
How are they maintained?
Simply swept and washed with a very mild cleaner (Easy Care Cleaner) and re-sealed when necessary, usually after 18 months.
How long will a Marshalls Tile floor last?
If properly laid and maintained then a Marshalls stone tile floor can last a lifetime.
Do the natural products require sealant?
We do recommend that these products are treated with a product to guard them against staining. Lithofin Stain Stop is recommended and is readily available both from Marshalls and other stone tile retailers.
Can they be used with underfloor heating?
Yes, very successfully when laid in a bed of flexible adhesive with a flexible grout, but please seek advice from a professional stone tiler.
Is electric underfloor heating expensive to run?
It is difficult to generalise, as running costs are determined by many different factors. However, when used within a well insulated building the cost is typically very low, averaging £3.00 - £4.00 per square metre per annum.
Can electric underfloor heating be used as the only heat source?
In the vast majority of cases the answer will be yes, especially in new, well insulated properties. The exception being old buildings with little or no insulation, rooms with doors and large windows and where you have limited floor space available.
How long is the order time?
This depends on stock levels at the time of ordering, and on the delivery service selected. In stock items are generally delivered within 7 working days.
Do we export our products?
Yes, we can and regularly do export our products to overseas customers. Please contact us for further advice.
Where can I see the stones?
View a list of local tile shops in your region.
Will the sample I receive be exactly the same as the product I receive?
All samples are a general indication only of texture and colour. Natural stone by its' very nature can vary and samples can be used as guidelines only.
Do you have to lay York/Pennant in courses?
No, both the Marshalls York and Marshalls Pennant can be laid randomly - see our laying patterns page.
Do I need to be present at the time of delivery?
It is important that you are available at the time of delivery, the delivery driver cannot handle the goods, so it is essential that you are there to receive the goods. All orders must be examined at the time of delivery and any damages or other discrepancies must be noted on the delivery note and reported to Marshalls within three days of receipt.
How do I store my stones?
Once delivered it is advisable to store the stones in dry conditions, the stones should be unpacked carefully and stacked vertically with a slight gap in between in order for the product to acclimatise and dry out from condensation that may have been present in the stone or the packaging.
What happens if I break a stone?
Normally when planning a floor an allowance is made for wastage in the quantity delivered, if a stone is chipped or broken these can normally be used for cuts within the floor.
How do I lay the stones?
It is always advisable to employ a professional fitter to install the product. We do provide detailed installation instructions which will provide guidance on the storage, preparation and laying of the product together with detailed information on how the different patterns of the product are laid.
