Great question John. Your assumption that your floor is tight during the summer months is partially correct. We usually encourage customers to apply Stop Creak late at night or first thing in the morning during the summer months to give it the best chance of penetrating. However, floors are a bit like stretching pizza dough. In the summer, they do expand but they do not expand equally - the expansion is more pronounced where sunlight hits the floor. In the winter, the floor contracts but will become tight around heat sources. If you have radiators this will be around the radiator and if the pipes to the radiator are under the floor, the floor above those pipes will expand. Therefore, if you want to achieve 100% silent floors we recommend applying Stop Creak then waiting 4-6 months or until the new season arrives. Creaks will usually start to appear in different areas than those you spot treated the first time round. If you spot treat the new areas you should find that once all the seasons have cycled, your floor is creaky free or as close to creak free as possible. Ultimately, Stop Creak is a penetrating lubricant that relies on chemistry and gravity to make its way into the tiny gaps of the floor that cause the friction. By being patient and applying over the seasons you should achieve a great result that lasts years. I hope that helps.

Hi Maria - I have checked our records and it appears you bought 2 x 120ml bottles of Stop Creak. We recommend to all customers that you do not any of our larger sizes before you have tried the product. Every floor is different and Stop Creak isn't a magical formula that can fix structural issues with floors. Simply put, Stop Creak is just a lubricant and if your floor still creaks after use then lubrication in the areas where you applied it is not the solution.
