Queries run slower because of the "joins".
It is necessary to assign relationships to interact with different tables
Data will lose when dinormalising.
Some disadvantages of normalization are that it creates an average, it is not precise, and takes away from the true results. This is helpful when determining overall results across many samples.
This web site give a good explanation of what disadvantages there are to database normalizations:

Un-normalization of data will return the actual values of outcome, which is real value. Because we scale the data in normalization process.
The purpose of normalization is to reduce the chances for anomalies to occur in a database. The Normalization also forces you to use a database in a Object orientated manner. (This is good of course.)

There are many advantages of performing a database normalization. Some of the advantages include faster index searching, data commands are faster with less indexes and a more compact database with less null data.
Normalization is the process of efficiently organizing data in a database. There are two goals of the normalization process: eliminating redundant data (for example, storing the same data in more than one table) and ensuring data dependencies make sense (only storing related data in a table). Both of these are worthy goals as they reduce the amount of space a database consumes and ensure that data is logically stored.

To decide on what tables to use for Data Normalization it will depend with the data that you have.
A person may get data normalization services in Florida from Gregg London. He runs U.P.C. Consulting and Data Normalization Services which is based in Florida.
Database normalization, or data normalization, is a technique to organize the contents of the tables for transactional databases and data warehouses. Normalization is part of successful database design; without normalization, database systems can be inaccurate, slow, and inefficient, and they might not produce the data you expect.
Database Normalization is the process of organizing the fields and tables of a relational database to minimize redundancy and dependency

Did you mean normalization or renormalization? Normalization involves determination of constants such that the value and first determinant of each segment of a wave function match at the intersections of the segments. Renormalization is a process to remove infinities from a wave function.
