Doors in Białystok — from your front step to every room

What doors do we offer?

In one place you can choose doors for the whole house with us — from a large terrace glazing to leaves for individual rooms. Each type has a different priority, so we don't sell one solution for everything. We'll tell you what really works for you.

PVC doors — terrace and entrance

Where a tight seal, light and resistance to moisture matter, PVC doors are the answer. The strongest item is the HS terrace door (tilt-and-slide) on a Salamander profile: huge glazing, an effortless slide and a low step-free threshold. Plus side-hung balcony doors and PVC side entrance doors. You'll find the details and full specification on the PVC doors page.

Brand-name exterior doors

An entrance door is the last barrier between the frost and the warmth inside. Our range includes warm, secure exterior doors from established manufacturers — with thermal insulation, thermal thresholds and multi-point locks. We'll recommend a class and finish to suit the façade; more on the exterior doors page.

Brand-name interior doors

Inside, what counts is keeping a room quiet, easy upkeep and a leaf that still closes smoothly after years. We have brand-name interior doors in various types and finishes, with adjustable frames for uneven walls. You'll find an overview on the interior doors page.

Why Pro-Plast?

We're a local Białystok firm with sales and fitting under one roof — we don't disappear once the doors are dropped off. The experience gathered over hundreds of jobs in and around Białystok shows best on tricky reveals and unusual thresholds.

• Straight advice — we tell you plainly what makes sense for your budget and what result to expect.
• Brand-name products — doors from established manufacturers and PVC terrace doors on Salamander profiles.
• One process from start to finish — measurement, order, delivery and fitting in one pair of hands.
• After-sales care — we're on hand should the hardware ever need adjusting.

If you're replacing your windows too, it's worth matching the colours — we'll show you the samples side by side so the whole thing comes together.

Measurement, fitting, guarantee and instalments

The worst thing you can do is buy doors by guesswork and leave the fitting to a random crew. With us it's a single process from measurement to adjusting the hardware.

1. Free on-site measurement — we come out, measure the opening and check the condition of the wall and threshold.
2. Free quote — we present specific models and prices in writing, with no charges for the obvious.
3. Delivery and professional fitting — we seat, level, seal and adjust.
4. After-sales care — we stay on hand after fitting.

We fit brand-name profiles, give a 5-year guarantee, and the purchase can be spread over instalments. We fit doors in the winter season too, using foams and materials suited to low temperatures.
