Welcome to
Trims & Windows

The business of Alphaplas Ltd was started in 1995 supplying to the trade and DIY, with PVCu fascia, soffit, cladding, trims etc, along with PVCu windows, doors, and conservatories. Due to a demand, from the general public, we finally established a fitting service.

The ‘retail’ side of the business grew to the stage that a sales manager was employed as well as five salesmen, telephone canvassers and foot canvassers to bring in the ‘leads’. Advertising by radio and posh magazines as well as newspapers, made the company very busy in Devon but more so in Cornwall.

After many years of trading we decided that we were like many other double glazing companies, employing high pressure sales techniques and carefully worded adverts with ‘special offers’ and ‘super discounts’ and if you need ‘selling to’ there are still plenty that will pin you in your own front room, until you sign up! Yes it still goes on!..

With our expansion we offer windows and doors in Saltash, Callington, Pensilva, Dobwalls, Plymouth, Tavistock and surroundings.

A long way down the road, with 90% of our business coming from recommendations,
we do not employ salespersons or offer unbelievable special discounts.

  • If you know what you want, and know the size, we will even give you a price on the telephone, obviously subject to survey.
  • If you do invite us to your home, one of the directors or fitter will visit, we don’t want to sit down a talk about the weather or politics! We will discuss your requirements and take some measurements.
  • We then leave and work out an accurate price and get any information that we were unable to provide when we visited you.
  • We will not try and stay any longer than you want us to.
  • We will then contact you with the price and answer any further questions that you may have or give advice that you may seek.
  • Most of all we are down to earth, honest, working class folk.
  • You are welcome to visit our SHOWROOM between 8 am and 3 pm Monday to Friday or by appointment any other time.
