We do insulation in Sant Andreu. We visit the property, assess the work, give you a clear price, and start. In winter, when humidity drops and the dry westerly wind comes in, wood contracts. The door closes well, but there’s a visible gap between the door and the frame, allowing air and noise to pass. This is wood's natural cycle and is only avoided in two ways. Either replace with a DM or multi-laminate door that doesn't expand and contract as much, or learn to live with it and adjust the hinges as needed.

The typical problem arises when you go to turn on the boiler or underfloor heating after eight months of disuse and it doesn't respond. The pump has seized, the expansion vessel has lost pressure, the thermostat has become unconfigured. We see it every November.
This is a very specific pattern for the area. Solid wood interior doors, especially those in blocks from the 80s-90s, swell and contract with seasonal humidity changes. In summer, when humidity and temperature are high, the wood absorbs water from the air and expands. The door stops closing properly, rubs the top or side frame, and forcing it shut only worsens the hinge. Traditional knob hinges, those seen on old construction doors, are not adjustable. If the door rubs, wood must be planed down or hinges replaced with modern adjustable models. Planing wood is the usual solution when the problem is seasonal. We remove 1-2 mm from the rubbing area, seal the cut, and the door closes again. We identify the real cause (humidity, settlement, worn hardware) before acting.
For more modern windows with tilt-and-turn profiles and thermal break, the hardware is of better quality but also requires maintenance. Lubricating hinges and adjusting closing points every 2-3 years significantly extends their lifespan and prevents air from entering in winter or them becoming too difficult to open.
