Do you offer a fitting service?
Yes, we offer a fitting service in the London and surrounding areas. Please look at our Fitting Service page to see if your post code is listed within this area.
Do you charge for deliveries?
Yes, we charge for deliveries, however if your order exceeds £850 delivery will be free in Areas A and B, and free if over £1,100 in Area C. We can deliver anywhere in Scotland as well as the Scottish Isles, Wales and England. Please look at our Delivery Options page to see what the current rates are for delivery – remember we have free delivery when orders are placed in excess of £750 in certain areas.
What are your returns policies?
Our returns policies can be found on the Returns Policy page. We do accept returns but the guidelines in the policy must be followed. We cannot offer refunds if the returns policies are not followed to the letter.
What are U Values and what do they mean?
A U value is a measure of heat loss and is used by Architects and Civil Engineers in designing the overall thermal characteristics and performances of a structure being constructed. It is expressed in W/m2k, and shows the amount of heat lost in watts (W) per square metre (/m2) of material (for example wall, roof, floor etc.) when the temperature (k) outside is at least one degree lower than the temperature inside the structure. The lower the U value, the better the insulation provided by the material used. Some external doors are therefore rated with a U value but only where they have been tested. Not all external doors have a U value rating.
How do I change between imperial and metric door sizes when looking at your product pages?
Each product shows a list of available sizes and the price for each size if different. The size is shown in both metric (mm) and inches (“).
What is a dowelled and a mortice & tenon construction?
A dowelled door has dowels glued into the joints between the stiles and rails of the door construction. This is a perfectly robust way of making a door. Other doors have a mortice & tenon joint between each of the stiles and rails and this is a much stronger constructed joint than a dowel joint. If a door we supply has mortice & tenon joints we list this fact on the individual product page.
What is an engineered construction in a door or frame?
A door has an engineered construction when the core of the door is made up from different materials to the face (or veneer) of the door. This means that some of the components have been made from other timbers to make either a laminated timber core, a chipboard solid or semi-solid core, a rigid lattice MDF (fibreboard) composite material core or even a hollow cardboard (eggshell construction) filled core.
FSC (Forestry Stewardship Council) guidelines on the use of sustainable materials meant a change in direction for the door industry from the original solid timber constructed doors of 20 years or so ago to the more robust, sustainable and therefore more Eco-friendly production of engineered products on sale nowadays. Engineered construction does offer a more efficient use of raw materials.
The performance of the product is also enhanced, through providing much greater stability in centrally heated houses where heat can dry out solid timber doors causing shakes (timber splits all the way through the grain of the door) or severe warping (where a radiator on high close to a door causes the door to ‘lean’ to the heat).
Engineered constructed doors allowed for the development of our modern flush and grooved / inlaid doors of today, offering much more variety of design and choice for the consumer. Overall the improved performance and design choice meant also a cheaper construction allowing the doors to not only become more versatile but affordable as well.
What guarantees come with each of the products?
We offer guarantees on all our products. These are manufacturer’s guarantees. Please look at our Guarantees page to review the details of each of our guarantees. Every item comes with a 10 year no-quibble guarantee, except where listed differently on individual products.
Some products only come with a 1 year manufacturer’s guarantee, and where this applies, it will be clearly listed.
Can I add to or change my order once it has being placed?
As long as the goods have not been dispatched or put into production (if bespoke) from the warehouse / factory prior to you wanting to add to or change an order, then generally, yes, we can effect changes to the order. If you forget something please contact us as soon as possible and we will certainly try our best to help you change your order.
If it is not possible to change your existing order, but a subsequent order is placed, we will try to carry out the deliveries at the same time, cutting the delivery costs if possible.
In all cases please refer to our Terms & Conditions of Sale for specific information that applies to your order.
What if I do not like my products when they arrive?
You have up to 14 days to decide to keep your goods under online distance selling rules. If you decide to return them, in a resalable condition – in the original untouched wrapping, you must inform us as per Section 9 of our Terms & Conditions of Sale. You will need to pay for the delivery charges to you (if you had a free delivery) and you must also pay the cost of return transport and insurance to cover any damages whilst the goods are being returned. Re-stocking and administration charges will also apply.
How much can I trim or cut-down a door on fitting?
The manufacturer’s advise that a door cannot be trimmed or cut-down excessively. By cutting or trimming a door by more than what they advise will void their warranties (guarantees).
No more than 4 to 6mm should be trimmed from any side, top or bottom of a door. However, in our experience with fitting doors, at times more may need to be cut from a door than the amounts recommended by the manufacturer’s. In this case we ask you, the client, to give us written permission to void your warranties on the doors supplied, so that the fitting can take place.
This is a call that only you can make. It is a risk that you may take, for example you buy an internal solid timber engineered panelled door from us and ask us to install it (or your own fitter) and it needs to be trimmed to 1945mm high from 1981mm (the original height), in this case if there was a manufacturer’s fault with the door which became visible after installation, you would not be covered by any warranty.
In our experience internal doors very rarely develop manufacturing faults and we would say that you probably would be okay in making the decision to cut-down the door.
If in any doubt please give us a call and we will be happy to advise you.
Do all your products comply with either the British Standards or Building Regs?
Where British Standards or Building Regs require either certificates for fire doors or PAS24 external doorsets or, for that matter, any locks or accessories for doors, we ensure that they are provided or that the products we supply conform to those regulations, as required.
Where we offer a fitting service for fire doors or external doors we ensure that our fitters install the doors inline with the regulations in force for that type of door.
We can supply, on request, fire certificates for all of our fire doors and can also provide certification documents for PAS24 external door sets as well.
If you have any questions regarding this please do not hesitate to contact us or email us on firstname.lastname@example.org.
Do your installers only fit doors that you supply?
Yes, we only install doors that we supply. Unfortunately we are unable to offer a fitting, repair or re-installation service on your own doors or doors that you have sourced from elsewhere.
Do you make custom sized doors, frames?
Yes, we manufacture custom sized external and internal doors as well as frames in both wood and steel. Our steel door and window range are also made here in the UK. You can have an escorted visit to the steel door factory to see doors being made. We also make bespoke wooden fire doors in the UK as well.
Do you have a showroom?
At present we do not have a showroom. Although this keeps our costs down and allows us to offer you fantastic prices against our competitors, we are planning to open a showroom in the London area in the future.
In the meantime you are able to visit the steel door and window factory.
If I have questions which are not listed in the FAQ's can I fill in a form to ask you?
