We do insulation in Sant Joan Despí. We visit the property, inspect the job, give you a clear price, and start work. This is a common fault in apartment blocks in Torrevieja and surrounding areas. PVC roller shutters with pull straps accumulate dust and debris in the side guides. The strap wears out over the years and sometimes breaks in mid-summer, leaving the shutter halfway down. If the strap is intact, the usual procedure is to clean the guides and lubricate the system with a specific product (not common oil, which attracts more dust).

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, rubbing against the top or side frame, and forcing it closed only worsens the hinge. In winter, when humidity drops and the dry westerly wind comes in, the wood contracts. The door closes well but there is a visible gap between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be avoided with two things. Either replace it with a MDF or multi-laminate door that doesn't have this movement, or learn to live with it and adjust the hinges occasionally. Traditional knob hinges, those seen on old-style doors, are not adjustable. If the door rubs, you have to shave off wood with a plane or replace the hinges with modern adjustable models. Shaving off 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.
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 entry in winter or them becoming too difficult to open. 400 euros for an installed condensing boiler, depending on brand, power, and necessary work. The replacement typically pays for itself in 4-6 years due to gas savings. Annual gas boiler maintenance, between 90 and 130 euros including certificate. Repair of a simple fault (sensor, valve, pressure switch), 80-180 euros plus parts. Complete replacement of a natural gas boiler with a condensing model, 1,400 euros including installation, depending on brand and power.
