    Had a front door with sidelights fitted as well as a side door to my home. From start to finish the service was second to none. Called up and they suggested popping into the showroom to look at the build quality and designs of the doors. Great knowledge and advice provided throughout, sat down and designed the doors in their office, took samples home to show my girlfriend. Price was very competitive for a product that was better than what was offered by other businesses. 2 weeks later and the doors have been installed. I was at the house when they were installing the doors and the two guys had no issues looking at (and resolving) an issue with the existing back door that needed a slight adjustment and answering a couple of questions and suggesting some resolutions to other areas in the property. Really appreciated!Popped into the showroom/office a couple of times through out the process and at all times all staff were extremely welcoming and helpful throughout the whole process. Would have no hesitation in recommending these guys to anyone who asks – I’ve had a couple of people ask where the doors are from since installation as we are documenting our renovation and I think you may have a couple of people heading your way!Got a couple of things to sort out throughout the year in regards to some windows and pitched roofing, I have no doubt that i’ll be heading your way!Thanks again!

  • A bit of a disaster really… 1) They took some time to agree when they could carry out a site visit (upvc patio windows /doors + side window + small roof lantern + canopy to existing carport). OK… I was prepared to be patient and wait a while;2) Then told it would be a week after the site visit that then happened (conducted by one of the partners in the business) before my quote could be prepared… it actually took 10 days..;3) When it did come, the proviso was they weren’t taking on any new building work currently (why bother with undertaking that part of the site visit then might you ask… ?? Why not tell me when they visited???);4) Only a v. small roof lantern, but Martindale’s was significantly the most expensive quote of the 3 I had. There was no sketch / diagram of any kind to indicate what it would look like nor what it would be constructed of / or a specification of it either;5) The patio doors required and indicated at the time of site visit were 4 panel design, but the quote received was based on an unrequested (cheaper to produce) two panel design which would not have worked visually (older style of house) or practically – the sliding door would have been c. 2 metres in width and therefore very heavy to operate for an older person such as myself.6) The quote totally ignored the removal of the old patio windows ( clue might be “not taking on any new building work..”!!) , so installing the new ones at the other side of the extension was now totally impractical as the old patio doors needed to be removed first through the new aperture.On the face of my experience … ‘too much work’ is equal to ‘too little interest’ in (potential) customers: the price was precise.. but sadly little else was. Look elsewhere I think if you are thinking of doors/ windows and spending £5-6k in the process.

    (Traducido por Google) Recomiendo encarecidamente Martindales. Tuvimos una antigua puerta de patio inclinable y deslizante reemplazada con nuevas puertas francesas con paneles laterales. Russ vino a medir muy pronto después de la llamada telefónica inicial, y llegó a tiempo. Me habló de mis opciones y escuchó atentamente mis requerimientos, haciendo sugerencias en el caminoMe citó un precio en el acto, sin presión en absoluto. Fui a la sala de exposición para ver el producto y fue recibido por él y Geoff, quien me mostró y respondió mis preguntas.No eran los más baratos (pero no estaban muy lejos), pero me inculcaron tanta confianza y el producto es de buena calidad que decidimos ir con ellos. ¡Las puertas se hicieron y ajustaron solo dos semanas después de que pagué el depósito! Una vez más, los instaladores Derek y Gavin llegaron a tiempo, fueron amables, ordenados y serviciales. Se desvivieron para estar atentos y garantizar que estuviéramos felices con el trabajo. ¡Y las nuevas puertas francesas se ven geniales!(Texto original)Highly recommend Martindales. We had an old tilt-and-slide patio door replaced with new French doors with side panels. Russ came along to measure up very soon after the initial phone call, and turned up on time. He talked me through my options and listened carefully to my requirements, making suggestions along the wayHe quoted me a price on the spot, with no pressure at all. I went along to the showroom to look at the product and was welcomed by him and Geoff who showed me around and answered my questions.They weren’t the cheapest (but not far off), but they instilled me with so much confidence and the product is of a good quality we decided to go with them. Doors were made and fitted only two weeks after I paid the deposit! Again, the fitters Derek and Gavin turned up on time, were polite, tidy and helpful They went out of their way to be attentive and ensured we were happy with the job. And the new French doors look great!
