Carpets get stained. That's what they do. This is the only thing a carpet can ever achieve during the course of its existence to make you even notice it in any way, shape or form. Whether it's coffee or ink stains, or maybe urine from pets (this is the worst kind of transgression against carpets), for one reason or another you can't clean the stain (or you don't want to).
I'm not going to treat you like an idiot if you're reading this then you've already made the decision to get rid of the old carpet and replace it. I will respect your wish and will provide some assistance on how to do it properly. I will not, at any point tell you that this is a bad idea. You're an intelligent, mature person and you know best. So, let's just get this over with.
How to remove the old carpet
There are a few things you need to think about before throwing away the carpet. How will you get it disposed of should be the first. Can you contact your local garbage disposal unit and request a special pick-up? Or should you just leave it in front and hope they will take it. Or maybe you need to dispose of it, yourself? You need to find the answers of these questions. Some garbage disposal representatives are insanely rude and would decline your request, as it's their right, even though that definitely shows that they are not the kind of people you can count on, anyway. Maybe they will agree to take it, but will get an extra fee. You need to know these things. Once you know how you will dispose of the carpet, it's to actually get to action by following these steps recommended by a Cricklewood carpet cleaning specialist.
Before throwing out the carpet you need to vacuum it first. If you don't, there will be lots of dust and other particles falling around and it will make a mess in your entire home, and the room the carpet used to cover will be the worst. That's why it's a good idea to vacuum it before you do anything else.
After you're done vacuuming, you need to move the furniture around so you can get the carpet out. You might need a bit of help here, so keep that in mind before you begin. Remove the old carpet (carefully) and get rid of it in the predetermined manner. Note: if you're getting your new carpet professionally installed, the company might agree to get rid of your old one for you so you might not have to do anything if you choose this option.
(Ahhh, picking out beautiful new carpet...)
Considerations and installation
Consider this what is the reason you had to replace the carpet? Was it a one time thing or is it something that happens all the time. Because if it happens all the time, there is not much you can do about it so you will have to replace carpets again and again. This is something I would assume you don't want to do. So if you think that this occurrence will repeat itself, you might want to consider a different sort of flooring. Something like tiles or laminate might be the perfect solution for you. Especially if it's in the dining room, or if you have pets, it would be much better for you.
If it was a one time accident and you're hell-bent on procuring a new carpet, then by all means, go for it. Just make sure you buy the one. Before you install it, clean the place well. This way the installation will go smoothly and you will be able to enjoy your new carpet.
